moralize

moralizeMAT

A directed acyclic graph represented either as a
    <code>graphNEL</code> object, an <code>igraph</code>, a (dense) <code>matrix</code>,
    a (sparse) <code>dgCMatrix</code>.

object

The representation of the moralized graph.
    When NULL the representation will be the same as the input object.

result

Moralize a directed acyclic graph which means marrying parents and
    dropping directions

utilities

The gRbase package provides general features
 which are used by other graphical modelling packages, in particular
 by the packages gRain, gRim and gRc.

   gRbase contains several datasets relevant for use in connection with
 	graphical models. Almost all datasets used in the book Graphical
	Models with R (2012) are contained in gRbase.

   gRbase implements several graph algorithms (based mainly on
 	representing graphs as adjacency matrices - either in the form
	of a standard matrix or a sparse matrix). Some graph
	algorithms are:
	(i) maximum cardinality search (for marked and unmarked graphs).
	(ii) moralize.
	(iii) triangulate.
	(iv) junctionTree.

   gRbase facilitates array operations,

   gRbase implements functions for testing for conditional independence.

   gRbase illustrates how hierarchical log-linear models (hllm) may be
 	implemented and describes concept of gmData (graphical meta
 	data). These features, however, are not maintained anymore and
 	remains in gRbase only because there exists a paper describing
	these facilities: A Common Platform for Graphical Models in R:
	The gRbase Package, Journal of Statistical Software, Vol 14,
	No 17, 2005.

   NOTICE Proper functionality of gRbase requires that the packages graph,
 	Rgraphviz and RBGL are installed from bioconductor; for
        installation instructions please refer to the webpage given below.
