barrierModel.define.RdDefine 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 or a = NA, 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 or a = NA, 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, default is FALSE, to indicate if the integral of the field over the domain is to be constrained to zero.
- debug
integer, default is zero, indicating the verbose level. Will be used as logical by INLA.
- useINLAprecomp
logical, default is TRUE, indicating if it is to be used the shared object pre-compiled by INLA. This is not considered if 'libpath' is provided.
- libpath
string, default is NULL, with the path to the shared object.
