gRbase (version 1.7-5)

graph-operations: Simple operations on undirected and directed acyclic graphs.

Description

Make operations on undirected and directed acyclic graphs (which are represented as graphNEL objects.

Usage

ancestors(set, object)
ancestralGraph(set, object)
ancestralSet(set, object)
children(set, object)
closure(set, object)
is.complete(object, set)
is.decomposition(set, set2, set3, object)
is.simplicial(set, object)
parents(set, object)
simplicialNodes(object)

Arguments

set, set2, set3

Vectors of sets

object

A graphNEL object

Details

Notice: graphNEL2adjMAT(g, result="matrix") and graphNEL2adjMAT(g, result="Matrix") do the same as as(g, "matrix") and as(g, "Matrix") but considerably faster.

Examples

uG <- ug(~me:ve,~me:al,~ve:al,~al:an,~al:st,~an:st)
closure("me", uG)
getCliques( uG )

amat1 <- graphNEL2M( uG )
getCliques( amat1 )

amat1 <- graphNEL2M( uG, result="Matrix" )
getCliques( amat1 )
