R Documentation

Define a spacetime model object for the `f()` call.

Description

Define a spacetime model object for the f() call.

Usage

barrierModel.define(
  mesh,
  barrier.triangles,
  prior.range,
  prior.sigma,
  range.fraction = 0.1,
  constr = FALSE,
  debug = FALSE,
  useINLAprecomp = TRUE,
  libpath = NULL
)

Arguments

`mesh`	a spatial mesh
`barrier.triangles`	a integer vector to specify which triangles centers are in the barrier domain, or a list with integer vector if more than one.
`prior.range`	numeric vector containing U and a to define the probability statements P(range < U) = a used to setup the PC-prior for range. If a = 0 then U is taken to be the fixed value for the range.
`prior.sigma`	numeric vector containing U and a to define the probability statements P(range > U) = a used to setup the PC-prior for sigma. If a = 0 then U is taken to be the fixed value for sigma.
`range.fraction`	numeric to specify the fraction of the range for the barrier domain. Default value is 0.1. This has to be specified with care in order to have it small enough to make it act as barrier but not too small in order to prevent numerical issues.
`constr`	logical to indicate if the integral of the field over the domain is to be constrained to zero. Default value is FALSE.
`debug`	logical indicating if to run in debug mode.
`useINLAprecomp`	logical indicating if is to be used shared object pre-compiled by INLA. This will not be considered if the argument `libpath` is provided.
`libpath`	string to the shared object. Default is NULL.
