Description

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

Usage

moralize(object, ...)

# S3 method for default moralize(object, result = NULL, ...)

Value

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

Arguments

object

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

...

Additional arguments, currently not used

result

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