genmodel: Generate a configuration matrix

Description

genmodel runs 4ti2's genmodel program to compute the configuration matrix A corresponding to graphical statistical models given by a simplicial complex and levels on the nodes.

Usage

genmodel(varlvls, facets, dir = tempdir(), quiet = TRUE, shell = FALSE, ...)

Value

The configuration matrix of the model provided

Arguments

varlvls

a vector containing the number of levels of each variable

facets

the facets generating the hierarchical model, a list of vectors of variable indices

dir

Directory to place the files in, without an ending /

quiet

If FALSE, messages the 4ti2 output

shell

Messages the shell code used to do the computation

...

Additional arguments to pass to the function

Examples

if (has_4ti2()) {

varlvls <- rep(2, 2)
facets <- list(1, 2)
genmodel(varlvls, facets)
genmodel(varlvls, facets, quiet = FALSE)

varlvls <- rep(3, 3)
facets <- list(1:2, 2:3, c(3,1))
genmodel(varlvls, facets)
