bru_mapper_matrix: Mapper for matrix multiplication

In inlabru-org/inlabru: Bayesian Latent Gaussian Modelling using INLA and Extensions

Mapper for matrix multiplication

Description

Create a matrix mapper, for a given number of columns

Usage

bru_mapper_matrix(labels)

## S3 method for class 'bru_mapper_matrix'
ibm_n(mapper, ...)

## S3 method for class 'bru_mapper_matrix'
ibm_values(mapper, ...)

## S3 method for class 'bru_mapper_matrix'
ibm_jacobian(mapper, input, state = NULL, inla_f = FALSE, ...)

Arguments

labels	Column labels for matrix mappings; Can be factor, character, or a single integer specifying the number of columns for integer column indexing.
mapper	A mapper S3 object, inheriting from bru_mapper.
...	Arguments passed on to other methods
input	Data input for the mapper.
state	A vector of latent state values for the mapping, of length ibm_n(mapper, inla_f = FALSE)
inla_f	logical; when TRUE for ibm_n() and ibm_values(), the result must be compatible with the INLA::f(...) and corresponding INLA::inla.stack(...) constructions. For ⁠ibm_{eval,jacobian,linear}⁠, the input interpretation may be different. Implementations do not normally need to do anything different, except for mappers of the type needed for hidden multicomponent models such as "bym2", which can be handled by bru_mapper_collect.
