Functions for converting graph objects into matrices
A graphNEL can be directly coerced into a adjacency matrix
using the as method. If the graph is undirected then the
matrix will by symmetric.
An adjacency
For aM2bpG, an object of class graphNEL. For
ftM2adjM, an adjacency matrix representation of the coerced graph.
