rspde.mesh.project: 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 = 1,
  loc = NULL,
  lattice = NULL,
  xlim = NULL,
  ylim = NULL,
  dims = c(100, 100),
  projection = NULL,
  ...
)
# S3 method for inla.mesh
rspde.mesh.project(
  mesh,
  loc = NULL,
  field = NULL,
  rspde.order = 1,
  nu = NULL,
  ...
)
# S3 method for rspde.mesh.projector
rspde.mesh.project(projector, field, ...)
# S3 method for inla.mesh.1d
rspde.mesh.project(mesh, loc, field = NULL, rspde.order = 1, nu = NULL, ...)

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.

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.
