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.
