In INLAspacetime: Spatial and Spatio-Temporal Models using 'INLA'

Illustrative code to build the projector matrix for SPDE models.

Description

Creates a projector matrix object.

Usage

mesh2projector(
  mesh,
  loc = NULL,
  lattice = NULL,
  xlim = NULL,
  ylim = NULL,
  dims = c(100, 100)
)

Arguments

mesh	a 2d mesh object.
loc	a two columns matrix with the locations to project for.
lattice	Unused; feature not supported by this illustration.
xlim, ylim	vector with the boundary limits.
dims	the number of subdivisions over each boundary limits.

Value

the projector matrix as a list with sparse matrix object at x$proj$A..

Warning

This is just for illustration purpose and one should consider the efficient functions available in the INLA and inlabru packages, e.g. inlabru::fm_evaluator.
