In inlabru: Bayesian Latent Gaussian Modelling using INLA and Extensions

Mapper for fm_mesh_2d

Description

Creates a mapper for 2D fm_mesh_2d objects. Equivalent to calling bm_fmesher().

Usage

## S3 method for class 'fm_mesh_2d'
bru_mapper(mesh, ...)

## S3 method for class 'bm_fm_mesh_2d'
ibm_n(mapper, ...)

## S3 method for class 'bm_fm_mesh_2d'
ibm_values(mapper, ...)

## S3 method for class 'bm_fm_mesh_2d'
ibm_jacobian(mapper, input, ...)

## S3 method for class 'bm_inla_mesh_2d'
ibm_n(mapper, ...)

## S3 method for class 'bm_inla_mesh_2d'
ibm_values(mapper, ...)

## S3 method for class 'bm_inla_mesh_2d'
ibm_jacobian(mapper, input, ...)

Arguments

mesh	An fm_mesh_2d object to use as a mapper
...	Arguments passed on to other methods
mapper	A mapper S3 object, inheriting from bru_mapper.
input	Data input for the mapper.

Value

A bm_fmesher object. Note: Prior to version ⁠2.12.0.9021⁠, this was a bru_mapper_fm_mesh_2d object. Also see the note for bru_mapper.fm_mesh_1d().
