class.convert: Convert graph object to adjacency matrix

Description

Convert graph object to adjacency matrix

Usage

class.convert(graph, convert = "matrix")

Arguments

graph

matrix, sparse matrix, igraph, edgelist, or network object

convert

class to convert to, one of "matrix", "sparseMatrix", "igraph", "edgelist", or "network"

Value

list(class, adjacency), a list containing the class of parameter graph, and the adjacency matrix of the graph

Details

An object is considered an edgelist if it is (1) a matrix or sparse matrix, and (2) has only two columns. Each column is understood as a bipartite set, with edges only going between members of column 1 and members of column 2.

davis.sp <- as(davis, "sparseMatrix")
