Deprecated functions in fmesher

Some of these functions still attempt to do their job, but will be removed in a future version.

Usage

fm_mesh_components(...)

fm_int_object(...)

fm_nonconvex_hull_inla(
  x,
  convex = -0.15,
  concave = convex,
  resolution = 40,
  eps = NULL,
  eps_rel = NULL,
  crs = NULL,
  ...
)

fm_nonconvex_hull_inla_basic(
  x,
  convex = -0.15,
  resolution = 40,
  eps = NULL,
  crs = fm_crs(x)
)

Arguments

...

Unused.

x

A spatial object

convex

numeric vector; How much to extend

concave

numeric vector; The minimum allowed reentrant curvature. Default equal to convex

resolution

integer; The internal computation resolution. A warning will be issued when this needs to be increased for higher accuracy, with the required resolution stated. For method="fm" only.

eps, eps_rel

The polygonal curve simplification tolerances used for simplifying the resulting boundary curve. See fm_simplify_helper() for details. For method="fm" only.

crs

Optional crs object for the resulting polygon. Default is fm_crs(x)

Value

fm_nonconvex_hull_inla() returns an fm_segm object, for compatibility with inla.nonconvex.hull().

Functions

• fm_mesh_components(): Backwards compatibility for fm_components(), deprecated since version 0.4.0.9001, disabled since 0.6.0

• fm_int_object(): Deprecated function since 0.5.0.9013; use new_fm_int() instead.

• fm_nonconvex_hull_inla(): Legacy method for INLA::inla.nonconvex.hull(). Use fm_nonconvex_hull() with method = "fm" instead, with either format = "fm" (for compatibility with code expecting fm_segm output) or format = "sf".

• fm_nonconvex_hull_inla_basic(): Special method fm_nonconvex_hull_fm() method for concave = 0. Requires splancs::nndistF().

INLA compatibility

For mesh and curve creation, the fm_rcdt_2d_inla() and fm_mesh_2d_inla() methods will keep the interface syntax used by the INLA::inla.mesh.create() and INLA::inla.mesh.2d() functions, respectively, whereas the fm_rcdt_2d(), fm_mesh_2d(), and fm_nonconvex_hull() interfaces may be different, and potentially change in the future. From version 0.4.0.9002, the fm_nonconvex_hull_inla() function is deprecated, in favour of the more configurable update version of fm_nonconvex_hull().
