Changelog

Source: NEWS.md

inlabru (development version)

New features

  • Add bru_names() method for extracting the inlabru standardised names of fixed effects, latent components, and hyperparameters from a fitted bru object. (version 2.13.0.9011)
  • Add bm_logitaverage() mapper, for weighted logit-averages (version 2.13.0.9010)

Updated features

  • Add bru_get_mapper() support for inla.cgeneric objects, and update the support for inla.rgeneric, to standardise where to store a pre-constructed mapper, so that external packages will no longer need to add their own bru_get_mapper() methods for their r/cgeneric sub-classes, if the mapper is pre-computed. (version 2.13.0.9005)
  • Remove unused group and replicate parts of each latent component, speeding up component evaluation and linearisation. (version 2.13.0.9006)
  • Allow index extraction from duplicated tags in bru_index(), returning all matching indices. (version 2.13.0.9014)
  • Code refactor and storage streamlining for bru_obs() to prepare for future extensions. (version 2.13.0.9015)
  • Add block_response element to bru_obs(aggregate_input) list input, to allow specifying a block-wise response variable to match for aggregated predictors. (version 2.13.0.9016)

Bug fixes

  • Fix logic for bru_set_missing<inla.surv>() to correctly handle the inla.surv() class variations (version 2.13.0.9002)
  • Handle changing number of hyperparameters in inla tracing (version 2.13.0.9004)
  • Robustify internal extended_bind_rows() method for unifying XY/XYZ sf coordinate columns (version 2.13.0.9009)

inlabru 2.13.0

CRAN release: 2025-07-09

New features

  • Allow the optional weights argument to bru_obs(family = "cp")/lgcp() to contain individual point observation weights, so that the eta contribution to the log-likelihood is sum(weights * eta) instead of sum(eta) (version 2.12.0.9006)
  • Automatically detect purely additive linear models (version 2.12.0.9014)
  • Add experimental predictor aggregation helper feature bru_obs(..., aggregate = ..., aggregate_input = ...) to simplify specification of models with aggregation as the final step of the predictor evaluation (version 2.12.0.9013, bugfix in 2.12.0.9016). Includes support for constructing the aggregation information, via domain,samplers, or precomputed ips (version 2.12.0.9022)
  • Add bru_set_missing() method for setting missing values in the bru_obs data, e.g. for use in cross-validation or prior sampling (version 2.12.0.9024)

Updates features

  • Add automated support for INLA models with hidden states, beyond the “bym” and “bym2” models (version 2.12.0.9002)
  • Add automatic mapper support for INLA lattice models “rw2d”, “rw2diid”, and “matern2d” (version 2.12.0.9004)
  • Add inputs data to the bru_info object, so that the component inputs can be pre-evaluated before automated mapper construction, and avoiding duplicate evaluation in iinla(). This can halve the pre-processing time for large spatial and spatio-temporal models (version 2.12.0.9010)
  • Add bru_log() data for warnings and errors reported by inlabru (version 2.12.0.9011)
  • Rename bru_like object class to bru_obs (version 2.12.0.9017) and temporarily re-reintroduce like_list() and bru_like_list() as aliases for bru_obs_list() (version 2.12.0.9020)
  • Add quantile argument to spde.posterior() for controlling the credible interval calculations, like materncov.bands(), which is now also exported (version 2.12.0.9019)
  • Remove dic and waic from default control.compute bru_options, to match INLA defaults (version 2.12.0.9024)

New and updated mapper features

  • The standard mapper class names have been shortened from bru_mapper_<type> to bm_<type>, to make code using them more readable. Objects of the old class names will be converted to the new classes internally, so that old stored objects will still work. Constructors of the form bru_mapper_<type>() call the corresponding new constructor bm_<type>() (version 2.12.0.9021)
  • Add bm_sum() mapper, for automated adding the output of multiple mappers, optionally with a single common input (version 2.12.0.9001)
  • Add interleaved option to bm_repeat() to allow interleaved states for summation of a repeated mapper (version 2.12.0.9001)
  • Allow n_block in input argument to bm_aggregate and bm_logsumexp evaluation methods, overriding the optional mapper object setting (version 2.12.0.9005)
  • (Note: due to the difficulty of ensuring correct output ordering, and fmesher will refuse character block input from version 0.5.0. Was: Allow character block information in bm_aggregate and bm_logsumexp mappers, from fmesher version 0.2.0.9017 (version 2.12.0.9013))
  • Expanded auto-detection of component sizes by checking Cmatrix and graph arguments, if present and n is NULL (version 2.12.0.9012)
  • Code refactor to expand bm_list mapper list handling, removing unnecessary method layers for component linearisation and simplification (version 2.12.0.9018)

Bugfixes and deprecations

  • Give deprecation warnings for Spatial object inputs to bru_obs(), as maintaining the fallback support code is becoming increasingly time-consuming, and the sf package is now the recommended spatial data handling package. (version 2.12.0.9023)
  • Bugfix for generate.bru() for evaluation of expressions in the absence of newdata (version 2.12.0.9007)
  • Use mid locations for ibm_values() for non-indexed fm_mesh_1d mapper (version 2.12.0.9009)
  • Deprecate the include and exclude arguments to predict() and generate() (version 2.12.0.9003)
  • Assumed that NROW() on the main component gave the correct size for group and replicate in the component _eval() feature. Now uses ibm_n_output() instead. Fixes #271 (version 2.12.0.9015)

inlabru 2.12.0

CRAN release: 2024-11-21

General changes

  • Introduce bru_obs() as a replacement to like(), to help avoid namespace clashes with e.g. data.table::like() (version 2.11.1.9026)
  • Change logic for bru_obs(allow_combine)/like() to allow user override, and add warnings for ambiguous cases (version 2.11.1.9011)
  • Add bru_response_size() method for extracting the response size for each observation bru_obs object (version 2.11.1.9013)
  • Add sf output format support for sline and spoly (version 2.11.1.9006)
  • Add [ and ] to special character set in bru_standardise_names() (version 2.11.1.9012)
  • Add bru_index() method for accessing predictor index information for sub-models, and a tag argument for bru_obs() to identify individual sub-models by name, which is also propagated to lists of bru_like objects (version 2.11.1.9017 and 2.12.0)
  • Allow bru_mapper_multi() sub-mappers to have non-zero offsets, that are added to generate the combined offset (version 2.11.1.9019)
  • Add general bru_mapper_fmesher() mapper, for indexed mapping of all objects supporting fm_dof() and fm_basis() (version 2.11.1.9021)
  • Add bru_mapper_repeat() mapper, for automated single-mapper sums (version 2.11.1.9022)

Data set updates

  • Convert mrsea to sf format (version 2.11.1.9009)
  • Convert the shrimp data set to sf format (version 2.11.1.9007)
  • Remove seals_sp data set due to excessive size (version 2.11.1.9010)
  • Replace the mexdolphin dataset with a function mexdolphin_sp() to avoid sp data objects in the package (version 2.11.1.9015)
  • Replace the gorillas dataset with a function gorillas_sp() to avoid sp data objects in the package (version 2.11.1.9016)

Namespace changes

  • Move sp from Imports to Suggests. Component definitions using coordinates as input require either sp::coordinates or sp having been already loaded with e.g. library(sp) (version 2.11.1.9003)
  • Remove ggmap support (version 2.11.1.9002)
  • Remove unnecessary INLA namespace loading in ggplot methods (version 2.11.1.9008)

  • Expand the summary and print method class coverage (version 2.11.1.9002)
  • Reduced the amount of diagnostic messages in bru_safe_inla() (version 2.11.1.9005)
  • Change name of component and component_list methods to bru_component and bru_component_list (version 2.11.1.9026)

inlabru 2.11.1

CRAN release: 2024-07-01

Bug fixes

  • Fix documentation link issues not spotted by local and github package checks
  • Work around invalid geometry in map data used by the Spatially Varying Coefficients vignette

inlabru 2.11.0

New features

  • Add support for the scale parameter to like().
  • Add support for special response objects like inla.mdata() and inla.surv(), when INLA version > 24.06.02 (for mdata) or > 24.06.26 (for surv) are available (version 2.10.1.9011)
  • New toypoints example data set, for basic modelling examples (version 2.10.1.9003)

Feature updates

  • Updated convergence plots, reducing random effect aspects to summary statistics, improving speed and visual coherence (version 2.10.1.9004)
  • Add options to bru_convergence_plot() to control the number of iterations shown, and optionally show the initial values that are stored from this version (version 2.10.1.9005)
  • Switch timing mechanism from Sys.time() to proc.time() to capture CPU time instead of elapsed clock time. Added bru_timings() method to extract the timings safely from a fitted bru object (version 2.10.1.9007 and 2.10.1.9010)
  • Add verbosity level information to the bru log data structure, allowing filtered log extraction and more flexible log display (version 2.10.1.9012)

Bug fixes

  • Fix regression bug in "bym" model support, where the latent state size wasn’t correctly handled by the mapper system (version 2.10.1.9002)
  • Add filter to limit mapper construction to only the components used in the predictor expression, to avoid unused components breaking the initialisation. This allows easier testing of multi-likelihood models (version 2.10.1.9006)
  • Improved backwards compatibility support for sp data input for family = "cp" (version 2.10.1.9008)

Deprecated methods

  • Deprecated (since 2.9.0) method ipoints(samplers, domain) is no longer available. Use fmesher::fm_int(domain, samplers) instead.
  • The allow_latent, include_latent arguments to like() have been deprecated in favour of the general bru_used() framework, that auto-detects what component effects and latent effects are used by a predictor expression.
  • The deprecated (since 2.8.0) cprod() method now gives a warning and will be removed in a future version. Use fmesher::fm_cprod() instead.
  • The integration_weight_aggregation method has been removed (deprecated since 2.8.0). Use fmesher::fm_vertex_projection() instead.
  • The mesh_triangle_integration method has been removed (deprecated since 2.8.0). Use fmesher::fm_int() instead.
  • Old use of bru_mapper.default() to define new mapper classes has been disabled (deprecated since 2.7.0). Use bru_mapper_define() instead.
  • Deprecated (since 2.8.0) methods is.inside(), vertices.inla.mesh(), and pixels() have been disabled. Use fmesher::fm_is_within(), fmesher::fm_vertices(), and fmesher::fm_pixels() instead.

inlabru 2.10.1

CRAN release: 2023-12-21

Feature updates

Bug fixes and dependency simplification

  • Remove dependence on the ggpolypath package, and the ggplot2::fortify.SpatialPolygons/DataFrame() methods that were deprecated in ggplot2 version 3.4.4. Code using gg.SpatialPolygons() together with coord_fixed()/coord_equal() for coordinate axis control needs to use coord_sf() instead.
  • Detect the need for vectorised parameters in bru_forward_transformation to allow bru_mapper_marginal to be applied with e.g. spatially varying parameters. (version 2.10.0.9001)
  • Detect terra version >= 1.7-66 that removes the need for detecting special cases (nrow(where) == 1 and terra::nlyr(data) == 1). Workaround code used for versions < 1.7-66. (version 2.10.0.9002) (Thanks to Robert J. Hijmans)

inlabru 2.10.0

CRAN release: 2023-10-29

Feature updates

  • Add new ibm_simplify() generic to handle mapper simplification more generally; needed to properly support non-linear component mappers. (version 2.9.0.9004)
  • Add new bru_mapper_marginal() mapper class that can be used as part of component mapper pipelines. (version 2.9.0.9004)
  • Add new ibm_eval2() generic that computes both evaluation and Jacobian, avoiding double-computing of the Jacobian, when practical. (version 2.9.0.9005)
  • Add new bru_timings_plot() function that plots the time used for each nonlinear iteration (version 2.9.0.9007)
  • Speed up bru_fill_missing() (by orders of magnitude) by changing method for finding the nearest available data point. (version 2.9.0.9011)
  • Add new bru_mapper_shift() mapper class that works like bru_mapper_scale() but for additive shifts instead of multiplicative scaling. (version 2.9.0.9012)
  • Added more checks for invalid component or predictor evaluations, to help catch user errors sooner, and with more informative messages. (version 2.9.0.9013)
  • Expand bru_mapper_matrix, previously used only for component model = "fixed", to allow integer indexing in addition to the previous factor/character-only indexing. (version 2.9.0.9014)

Bug fixes

  • The is_linear flag wasn’t correctly set for bru_mapper_logsumexp mappers. Since previous versions did not accept non-linear component mappers, this is unlikely to have affected any user code. (Fixed in version 2.9.0.9001)
  • Improved error messages for missing or incomplete LGCP domain specification. (version 2.9.0.9002 and 2.9.0.9006)
  • Allow NULL in automatic component usage detection. (version 2.9.0.9003)
  • Corrected the crs information for gorillas$plotsample$counts and gorillas_sf$plotsample$counts from +units=m to +units=km. (version 2.9.0.9010) The geometry information in counts is unlikely to have been used in examples or analysis code, as the problem would have been immediately obvious; plotting or other geometric operations that use the crs information would heve been completely wrong, and is only detected now that more code uses the crs information at all. Thanks to Dmytro Perepolkin for reporting in issue #205
  • Fix problem in bru_fill_missing() for cases where the input data object also has missing values. (version 2.9.0.9011)
  • Make eval_spatial() transform the where coordinates to the same crs as the input data, for SpatRaster and sf inputs, to allow different crs specifications. (version 2.9.0.9012)

inlabru 2.9.0

CRAN release: 2023-08-28

Feature updates

  • Conversion of code to use fmesher for mesh and geometry handling; the interface supports existing objects and methods. See https://inlabru-org.github.io/fmesher/articles/inla_conversion.html for more information.

  • General speed improvements, see below for details.

  • Added gg.sf() method.

  • Add experimental support for stars via eval_spatial(). (version 2.8.0.9007)

  • Move the sp package from ‘Depends’ to ‘Imports’. This means that user code should either use sp:: or library("sp") to access sp methods. The bru_safe_sp() helper function can be used to check for a safe sp package configuration during the transition from rgdal to sf, and is only needed if you may run on systems with sp installations older than “2.0-0” or with sp::get_evolution_status() < 2. (version 2.8.2011)

  • Now preserves the previous log output when using bru_rerun(), and bru_log() is now a set of S3 methods, supporting extracting the full inlabru log as well bru-object specific logs (version 2.8.0.9008).

    Note: From version 2.9.0, use bru_log() to access the global log, and bru_log(fit) to access a stored estimation log.

    Up to version 2.8.0, bru_log() was a deprecated alias for bru_log_message(). When running on 2.8.0 or earlier, use bru_log_get() to access the global log, and cat(fit$bru_iinla$log, sep = "\n") to print a stored estimation object log.

Bug fixes and speed improvements

  • Covariate object component inputs of type SpatialPolygonsDataFrame were not automatically passed on to eval_spatial(). The logic has now changed so that any object with a eval_spatial() method will trigger a call to eval_spatial(). See ?input_eval for further information. (version 2.8.0.9001)
  • fm_crs_is_null(), fm_transform() now supports oblique fm_crs CRS objects, and is.na() methods for the fm_crs and inla.CRS classes have been added. (version 2.8.0.9003)
  • Significant speed up predict() by using quantile(..., names = FALSE). (version 2.8.0.9004)
  • Improved row_kron() code, causing speedups of a factor 2-30 in randomised test cases. (version 2.8.0.9005)
  • Removed incorrect code for sf method for eval_spatial(), causing failure when extracting from multiple layers in a single call. (version 2.8.0.9007)
  • Improved handling of posterior sample variable extraction in generate() and predict(). Now much faster for large models. (version 2.8.0.9009)
  • Fixed linearisation issue when using only the *_latent form of a component. (version 2.8.0.9015)
  • Workaround for equivalent but textually different CRS/WKT information in bru_fill_missing(). (version 2.8.0.9016, fixes #200)

Deprecation of old functions

  • eval_SpatialDF removed, deprecated since 2.8.0. See eval_spatial instead.
  • stransform, ibm_amatrix, ibm_valid_input removed, deprecated since 2.7.0. See fm_transform and ibm_jacobian instead.
  • bru_mapper_offset, deprecated since 2.6.0 now returns a pure bru_mapper_const object, and all bru_mapper_offset ibm_* methods have been removed.
  • init.tutorial removed, deprecated since 2.5.0
  • generate.inla and predict.inla removed, deprecated since 2.1.0

inlabru 2.8.0

CRAN release: 2023-06-20

Feature updates

  • The iterative inla method has been given both sharper internal inla() optimisation criteria for the iterations (thanks to Haavard Rue), and a more relaxed nonlinear iteration stopping criterion; the default bru_method$rel_tol values has been changed from 1 to 10 percent change. The iterations are terminated when all latent and hyper-parameter mode changes fullfil |change|/SD < rel_tol, and the non-linear line search is inactive. This seems to strike a useful balance between the different optimisation criteria, allowing the iterations to converge faster and also detect that convergence sooner.

  • The logic for which components are needed for a predictor expression (in like() or generate()/predict()) has been updated to when possible extract the list of components from the expression itself. The user can override this default if necessary, using the include/exclude arguments.

    The bru_used() methods are used to guess the needed component names, applied to the right-hand side of the formula arguments. The allow_latent argument to like() has been deprecated in favour of include_latent (by default auto-detected for use of _latent and _eval).

    The internal information storage is handled by the new bru_used() methods, that can also be used directly by the user and supplied via the used argument to like()/generate()/predict().

  • Add fm_int() integration methods, replacing the old ipmaker() and ipoints() methods. Supports both sf and sp sampler objects.

  • Add fm_pixels() methods for gridded points. The old pixels() method now calls fm_pixels(..., format = "sp")

  • eval_spatial support for sf objects (for point-in-polygon data lookups)

  • Allow precomputed spatial covariates in the data for point process observations

  • Add edge|int|ext.linewidth arguments to gg.inla.mesh #188

  • Rename the predict() and generate() data arguments to newdata, for better compatibility with other predict() methods. The old argument name will still be accepted, but give a warning. Code that does not name the data argument is not affected.

  • Note: Coordinate names for Spatial* objects have been inconsistently available in the predictor expression evaluation. However, due to how internal conversions might inadvertently change these names, they can not be relied on, and they are no longer being made available to the predictor expression. As a side effect, this change also speeds up some bru() runs by around a factor 2, since it avoids converting the Spatial* to a regular data.frame in time-sensitive core evaluation code.

    If you need access to the raw coordinate values, use explicit calls to sp::coordinates(.data.) (e.g. for custom spatial covariate evaluation.). When possible, use the built-in covariate evaluation method, eval_spatial(), either implicitly with comp(covariate, ...) or explicitly, comp(eval_spatial(covariate, where = .data.), ...), that handles crs information correctly. Also consider transitioning from sp to sf data storage, using geometry instead of raw coordinates.

Bug and dependency updates

  • Remove rgdal and maptools dependencies #178
  • Add bru_safe_sp() to check if sp can be used safely (checks rgdal availability and sp evolution status, optionally forcing use of sf) #178
  • Remove PROJ4 support #178
  • Change rgl.* functions to *3d. Thanks to Duncan Murdoch #181
  • Speed up ibm_jacobian.bru_mapper_harmonics for large models
  • Add workarounds for inconsistent polygon orientation resulting from sf::st_* calls that don’t account for the geos canonical representation being CW, whereas the canonical Simple Features representation being CCW. See https://github.com/r-spatial/sf/issues/2096

inlabru 2.7.0

CRAN release: 2022-12-02

Feature overview

  • Added support for sf and terra inputs to most methods
  • Expanded geometry and mesh handling methods
  • Expanded bru_mapper() system
  • Added convergence diagnostics plot with bru_convergence_plot()

Feature details

Bug fixes

  • Remove unused spatstat.core dependency. Fixes #165
  • Fixed issue with plain mapper evaluation in the ibm_eval.default() and ibm_eval.bru_mapper_collect() methods, where they would return zeros instead of the intended values. The main component evaluation and estimation code was not directly affected as that is based on the bru_mapper_multi() class methods that rely on the Jacobians instead. The bug would therefore mainly have impacted the future, not yet supported nonlinear mapper extensions.
  • Fix for eval_spatial.SpatRaster; Work around inconsistent logic in terra::extract(..., layer) when length(layer)==1 or nrow(where)==1. Fixes #169
  • Add indexed logical option to bru_mapper_factor(), to allow factor inputs to be mapped to index values, as needed for group and replicate. Fixes #174

inlabru 2.6.0

CRAN release: 2022-10-24

Features

  • Add bru_get_mapper generic, and associated methods for inla.spde and inla.rgeneric objects. This allows inlabru to automatically extract the appropriate bru_mapper object for each model component, and can be used as a hook by external packages implementing new INLA object classes.

  • Add a weights argument for like(), for likelihood-specific log-likelihood weights, passed on to the INLA::inla() weights argument. Evaluated in the data context.

  • The <component>_eval() methods available in predictor expressions now handle optional scaling weights, like in ordinary component effect evaluation.

  • Add terra support for covariate inputs

  • The component *_layer arguments are now evaluated in the data context, to allow dynamic layer selection for spatial raster covariates. A new generic eval_spatial() provides support for grid/pixel based Spatial*DataFrame evaluation, and SpatRaster. Expanded support is in progress.

  • New vignettes on the bru_mapper system, component definitions, and prediction_scores

  • General overhaul of the bru_mapper and linearised predictor system, to prepare for new features.

    • Add ibm_eval generic for evaluating mappers for given states.
    • Add bru_mapper_taylor, used as an internal mapper for linearised mappers. This and ibm_eval is aimed at future support for nonlinear mappers. Associated new generic methods: ibm_{is_linear,jacobian,linear}.
    • New mapper implementations should use ibm_jacobian instead of ibm_amatrix. This allows defining a linearised mapper via ibm_eval(input, state0) + ibm_jacobian(input, state0) %*% (state - state0).
    • New mapper class bru_mapper_const, which replaces bru_mapper_offset. bru_mapper_offset is now deprecated and will produce warnings.

Bug fixes

  • Enable both datum/ensemble container for ellipsoid information, to support epsg:4326. Fixes #154
  • Make duplicated component names an error instead of a warning. Relates to #155
  • Fix Tsparse assumptions in row_kron to prepare for Matrix 1.5-2. Fixes #162

inlabru 2.5.3

CRAN release: 2022-09-05

Features

  • Add bru_mapper_harmonics mapper for cos and sin basis sets.
  • Allow predict() input data to be be a list.
  • Allow arbitrary quantile summaries in predict()
  • Remove cv, var, smin, smax summaries from predict()
  • Add mean.mc_std_err and sd.mc_std_err output to predict()
  • Add robins_subset data set and associated variable coefficient web vignette

Bug fixes

  • Propagate multi-likelihood A-matrix information instead of recomputing. Fixes iteration issue for bym2 and other bru_mapper_collect models.
  • Turn on predictor summaries during iterations to allow inla.mode="classic" to use proper line search.
  • Avoid deprecated Matrix (>=1.4-2) class coercion methods
  • Work around for lack of full Matrix and ModelMatrix support for the unique method. Fixes #145

inlabru 2.5.2

CRAN release: 2022-03-30

  • More robust package checks
  • More robust namespace and INLA availability checks
  • Add package vignette with links to the website examples

inlabru 2.5.1

  • Revert to R language features compatible with R 4.0.5
  • Use strategy="gaussian" during iterations.

inlabru 2.5.0

CRAN release: 2022-03-21

Features

  • Add bru() timing information in $bru_timings and $bru_iinla$timings
  • Add SpatialPolygonsDataFrame support to gg() methods
  • Allow accessing E and Ntrials from response_data and data (further special arguments remain to be added)
  • deltaIC improvements
  • New transformation helper tools bru_{forward/inverse}_transformation()
  • Experimental support for matrix and formula component inputs. E.g. with ~ name(~ -1 + a + b + a:b, model = "fixed"), covariate fixed effect interaction specifications can be made. For formula input, MatrixModels::model.Matrix() is called to construct matrix input that is then used as the A-matrix for fixed effects, one per column, added up to form the combined effect.
  • Documentation and examples improvements

Bug fixes

  • Fix A-matrix construction for evaluate_model() for cases where the inla_f argument matters
  • More efficient and robust mesh integration code
  • Cleanup of environment handling for component lists

inlabru 2.4.0

CRAN release: 2021-12-19

Features

  • Allow predictors to have different size than the input data. The data argument is now allowed to be a list(), and the new argument response_data allows separate specification of component inputs and response variables.
  • Add bru_mapper_collect class for handling sequential collections of mappers, including collections where all but the first mapper is hidden from the INLA::f() arguments n and values, as needed to support e.g. “bym2” models.
  • Add control.family as a direct argument to like(). Gives a warning if a control.family argument is supplied to the the options argument of bru(), but at least one likelihood has control.family information. (Issue #109)

Bugfixes

  • Fix support for SpatialPointsDataFrame and SpatialGridDataFrame input to bru_fill_missing()
  • Force explicit model = "offset" components instead of special options, to avoid interfering with the linearisation system (Issue #123)
  • Make the iterations more robust by resetting the internal INLA predictor states to initial value zero at each step

Miscellaneous

  • Rename the option bru_method$stop_at_max_rel_deviation to bru_method$rel_tol. Automatic conversion to the new name, but a warning is given.
  • Add option bru_method$max_step to control the largest allowed line search scaling factor. See ?bru_options
  • New default option bru_compress_cp set to TRUE to compress the predictor expression for family="cp" to use a single element for the linear predictor sum.

inlabru 2.3.0

CRAN release: 2021-03-16

Breaking changes since version 2.1.13

  • The model component argument map has been deprecated. Use main to specify the main component input, ~ elev(main = elevation, model = "rw2"). Unlike the old map argument, main is the first one, so the shorter version ~ elev(elevation, model = "rw2") also works.
  • Intercept-like components should now have explicit inputs, e.g. ~ Intercept(1) to avoid accidental confusion with other variables.
  • The argument list for bru() has been simplified, so that all arguments except components and options must either be outputs from calls to like(), or arguments that can be sent to a single like() call.
  • The option setting system has been replaced with a more coherent system; see ?bru_options() for details.
  • The samplers and domain system for lgcp models is now stricter, and requires explicit domain definitions for all the point process dimensions. Alternatively, user-defined integration schemes can be supplied via the ips argument.

New features since version 2.1.13

  • The model component input arguments main, group, replicate, and weights can now take general R expressions using the data inputs. Special cases are detected: SpatialPixels/GridDataFrame objects are evaluated at spatial locations if the input data is a SpatialPointsDataFrame object. Functions are evaluated on the data object, e.g. field(coordinates, model = spde)
  • The component arguments mapper, group_mapper, and replicate_mapper can be used for precise control of the mapping between inputs and latent variables. See ?bru_mapper for more details. Mapper information is automatically extracted from INLA::inla.spde2.pcmatern() model objects.
  • The R-INLA weights and copy features are now supported.
  • The predictor expressions can access the data object directly via .data.
  • If data from several rows can affect the same output row, the allow_combine = TRUE argument must be supplied to like()
  • The include and exclude arguments to like(), generate(), and predict() can be used to specify which components are used for a given likelihood model or predictor expression. This can be used to prevent evaluation of components that are invalid for a likelihood or predictor.
  • Predictor expressions can access the latent state of a model component directly, by adding the suffix _latent to the component name, e.g. name_latent. For like(), this requires allow_latent = TRUE to activate the needed linearisation code for this.
  • Predictor expressions can evaluate component effects for arbitrary inputs by adding the suffix _eval to access special evaluator functions, e.g. name_eval(1:10). This is useful for evaluating the 1D effect of spatial covariates. See the NEWS item for version 2.2.8 for further details.
  • The internal system for predictor linearisation and iterated INLA inference has been rewritten to be faster and more robust
  • See the NEWS entries for versions 2.1.14 to 2.2.8 for further details on new features and bug fixes

inlabru 2.2.8

  • Add _eval suffix feature for generate.bru and predict.bru, that provides a general evaluator function for each component, allowing evaluation of e.g. nonlinear effects of spatial covariates as a function of the covariate value instead of the by the spatial evaluator used in the component definition. For example, with components = ~ covar(spatial_grid_df, model = "rw1"), the prediction expression can have ~ covar_eval(covariate), where covariate is a data column in the prediction data object.

    For components with group and replicate features, these also need to be provided to the _eval function, with ..._eval(..., group = ..., replicate = ...)

    This feature is built on top of the _latent suffix feature, that gives direct access to the latent state variables of a component, so in order to use _eval in the model predictor itself, you must use like(..., allow_latent = TRUE) in the model definition.

inlabru 2.2.7

  • Add support for ngroup and nrep in component definitions
  • Updated mexdolphin and mrsea data sets, with consistent km units and improved mesh designs

inlabru 2.2.6

  • Add predict(..., include) discussion to distance sampling vignette, for handling non-spatial prediction in spatial models.
  • Fix bugs in gg.SpatialLines

inlabru 2.2.5

  • Vignette corrections
  • Documentation improvements
  • Fix minor bug in Spatial* object handling and plotting

inlabru 2.2.4

  • Properly extract the joint latent conditional mode instead of the marginal latent conditional mode

inlabru 2.2.2

  • Fixed issue with predict() logic for converting output to Spatial*DataFrame
  • Use control.mode=list(restart=FALSE) in the final inla run for nonlinear models, to avoid an unnecessary optimisation.
  • Fix issues in pixels() and bru_fill_missing() for Spatial*DataFrame objects with ncol=0 data frame parts.

inlabru 2.2.1

  • Fixed code regression bug for function input of covariates

inlabru 2.2.0

  • Support for the INLA “copy” feature, comp2(input, copy = "comp1")
  • Allow component weights to be an unnamed parameter, comp(input, weights, ...)
  • Direct access to the data objects in component inputs and predictor expressions, as .data., allowing e.g. covar(fun(.data.), ...) for a complex covariate extractor method fun()
  • Partial support for spherical manifold meshes
  • Uses INLA integration strategy “eb” for initial nonlinear iterations, and a specified integration strategy only for the final iteration, so that the computations are faster, and uses the conditional latent mode as linearisation point.

inlabru 2.1.15

  • New options system
  • New faster linearisation method
  • New line search method to make the nonlinear inla iterations robust
  • Method for updating old stored estimation objects
  • System for supplying mappings between latent models and evaluated effects via bru_mapper objects
  • Improved factor support; Either as “contrast with the 1st level”, via the special "factor_contrast" model, or all levels with model "factor_full". Further options planned (e.g. a simpler options to fix the precision parameter). The estimated coefficients appear as random effects in the inla() output.
  • Interface restructuring to support new features while keeping most backwards compatibility. Change map= to main= or unnamed first argument; Since main is the first parameter, it doesn’t need to be a named argument.
  • Keep components with zero derivative in the linearisation
  • PROJ6 support
  • Add random seed option for posterior sampling
  • Add package unit testing
  • New backend code to make extended feature support easier
  • New int.args option to control spatial integration resolution, thanks to Martin Jullum (martinju)
