graph-moralize: Moralize a directed acyclic graph
In gRbase: A Package for Graphical Modelling in R

Description Usage Arguments Value Note Author(s) See Also Examples

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

moralize(object, ...)

## Default S3 method:
moralize(object, result = NULL, ...)

`object`	A directed acyclic graph represented either as a `graphNEL` object, an `igraph`, a (dense) `matrix`, a (sparse) `dgCMatrix`.
`result`	The representation of the moralized graph. When NULL the representation will be the same as the input object.
`...`	Additional arguments, currently not used

A moralized graph represented either as a graphNEL, a dense matrix or a sparse dgCMatrix.

The workhorse is the moralizeMAT function.
