make_mesh function

Make an R-INLA mesh based off a grid

This will make a mesh based off a given grid. Ideally the mesh construction and validation should be done by hand, but this exists for convenience. Meshes are used for sim_ays_covar_spde. The defaults are designed for the default grid. Just a basic interface between the grid and inla.mesh.2d.

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

Arguments

• grid: grid object to make a mesh of
• max.edge: The largest allowed triangle edge length. One or two values. This is passed to inla.mesh.2d
• bound.outer: The optional outer extension value given to offset.
• cutoff: Minimum distance allowed between points
• offset: The automatic extension distance given to inla.mesh.2d
• ...: Other options to pass to inla.mesh.2d

Returns

Returns an object of class inla.mesh.

Examples

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