Make an R-INLA mesh based on a grid — make

This function creates a mesh based on a given grid. While mesh construction and validation should ideally be done manually, this function provides a convenient default interface between a grid and inla.mesh.2d. It is designed to support usage with sim_ays_covar_spde(), and the default parameters are tuned for use with the default grid setup.

make_mesh(
  grid = make_grid(),
  max.edge = 50,
  bound.outer = 150,
  cutoff = 10,
  offset = c(max.edge, bound.outer),
  ...
)

Arguments

grid: A grid object to generate a mesh from.
max.edge: The maximum allowed triangle edge length. One or two numeric values. Passed to inla.mesh.2d.
bound.outer: Optional outer extension value passed to offset.
cutoff: Minimum distance allowed between mesh points.
offset: Automatic extension distance used by inla.mesh.2d.
...: Additional options passed to inla.mesh.2d.

Value

An object of class inla.mesh.

Examples

# \donttest{
if (requireNamespace("INLA")) {
  basic_mesh <- make_mesh()
  plot(basic_mesh)
}
