Find index subset of INLA visible states

Implementations must return a logical vector of TRUE/FALSE for the subset such that, given the full A matrix and values output, A[, subset, drop = FALSE] and values[subset] (or values[subset, , drop = FALSE] for data.frame values) are equal to the inla_f = TRUE version of A and values. The default method uses the ibm_values output to construct the subset indexing.

Usage

ibm_inla_subset(mapper, ...)

# Default S3 method
ibm_inla_subset(mapper, ...)

Arguments

mapper

A mapper S3 object, inheriting from bru_mapper.

...

Arguments passed on to other methods

Value

A logical vector of TRUE/FALSE for the subset such that, given the full A matrix and values output, A[, subset, drop = FALSE] and values[subset] (or values[subset, , drop = FALSE] for data.frame values) are equal to the inla_f = TRUE version of A and values.

Methods (by class)

• ibm_inla_subset(default): Uses the [ibm_values()] output to construct the inla subset indexing as the difference between inla_f=FALSEandinla_f=TRUE. Extra arguments such as multiare passed on to [ibm_values()]. This means it supports both regular vector values andmulti=1` data.frame values.
