Create mapper for an fm_mesh_1d object
Usage
# S3 method for class 'fm_mesh_1d'
bru_mapper(mesh, indexed = TRUE, ...)
# S3 method for class 'bm_fm_mesh_1d'
ibm_n(mapper, ...)
# S3 method for class 'bm_fm_mesh_1d'
ibm_values(mapper, ...)
# S3 method for class 'bm_fm_mesh_1d'
ibm_jacobian(mapper, input, ...)
# S3 method for class 'bm_inla_mesh_1d'
ibm_n(mapper, ...)
# S3 method for class 'bm_inla_mesh_1d'
ibm_values(mapper, ...)
# S3 method for class 'bm_inla_mesh_1d'
ibm_jacobian(mapper, input, ...)Arguments
- mesh
An
fm_mesh_1dobject to use as a mapper- indexed
logical; If
TRUE(default), theibm_values()output will be the integer indexing sequence for the latent variables (needed forspdemodels). IfFALSE, points representative of the basis centres are returned (useful for an interpolator forrw2models and similar, forfmesherversions>= 0.3.0.9002).- ...
Arguments passed on to other methods
- mapper
A mapper S3 object, inheriting from
bru_mapper.- input
Data input for the mapper.
Value
A bm_fm_mesh_1d or bm_fmesher object. The the
general bm_fmesher() mapper handles all indexed fmesher
objects.
