graph-coercion: Coercion of graphs

Description

Coercion of graphs from graphNEL format to dense or sparse adjacency matrix formats etc.

Usage

as.adjMAT(object, result="matrix")
graphNEL2M(object, result="matrix")
graphNEL2MAT(object, limit=100)
graphNEL2ftM(object)
graphNEL2matrix(object)
graphNEL2dgCMatrix(object)

Arguments

object

A graphNEL object

result

Either "matrix" of "Matrix" (or equivalenty "dgCMatrix") for a sparse matrix representation.

limit

If the number of nodes is larger than limit the matrix will be sparse; otherwise dense.

Details

Notice: graphNEL2M(g, result="matrix") and graphNEL2M(g, result="Matrix") do the same as as(g, "matrix") and as(g, "Matrix") but considerably faster.
