Examples

## Not run: 

# 2x2 independence example
# following convention, the first index indicates rows
varlvls <- c(2,2)
facets <- list(1,2)
( A <- hmat(varlvls, facets) )
markov(A)
markov(A, "vec")
markov(A, "tab", varlvls)
markov(A, "tab", varlvls, TRUE)
tableau(markov(A), varlvls)






# LAS example 1.2.12, p.17  (no 3-way interaction)
varlvls <- c(2,2,2)
facets <- list(c(1,2), c(1,3), c(2,3))
( A <- hmat(varlvls, facets) )
markov(A)
