R Documentation

Calculate a lattice projection to/from an `inla.mesh` for rSPDE objects

Description

Calculate a lattice projection to/from an inla.mesh for rSPDE objects

Usage

rspde.mesh.project(...)

rspde.mesh.projector(
  mesh,
  nu = NULL,
  rspde.order = 2,
  loc = NULL,
  lattice = NULL,
  xlim = NULL,
  ylim = NULL,
  dims = c(100, 100),
  projection = NULL,
  ...
)

## S3 method for class 'inla.mesh'
rspde.mesh.project(
  mesh,
  loc = NULL,
  field = NULL,
  rspde.order = 2,
  nu = NULL,
  ...
)

## S3 method for class 'rspde.mesh.projector'
rspde.mesh.project(projector, field, ...)

## S3 method for class 'inla.mesh.1d'
rspde.mesh.project(mesh, loc, field = NULL, rspde.order = 2, nu = NULL, ...)

Arguments

`...`	Additional parameters.
`mesh`	An `inla.mesh` or `inla.mesh.1d` object.
`nu`	The smoothness parameter. If `NULL`, it will be assumed that nu was estimated.
`rspde.order`	The order of the rational approximation.
`loc`	Projection locations. Can be a matrix or a SpatialPoints or a SpatialPointsDataFrame object.
`lattice`	An `inla.mesh.lattice` object.
`xlim`	X-axis limits for a lattice. For R2 meshes, defaults to covering the domain.
`ylim`	Y-axis limits for a lattice. For R2 meshes, defaults to covering the domain.
`dims`	Lattice dimensions.
`projection`	One of c("default", "longlat", "longsinlat", "mollweide").
`field`	Basis function weights, one per mesh basis function, describing the function to be evaluated at the projection locations.
`projector`	A `rspde.mesh.projector` object.

Details

This function is built upon the inla.mesh.project and inla.mesh.projector functions from INLA.

Value

A list with projection information for rspde.mesh.project. For rspde.mesh.projector(mesh, ...), a rspde.mesh.projector object. For rspde.mesh.project(projector, field, ...), a field projected from the mesh onto the locations given by the projector object.
