perms {GraphAT}R Documentation

Randomly permute edges or node labels in a graph

Description

Given an adjacency matrix for a graph, permEdgesM2M will return an adjacency matrix after an Erdos-Renyi random permutation of the edges in the graph. perNodesM2M will return an adjacency matrix for a graph with identical structure, but with the node labels permuted.

Usage

permEdgesM2M(mat)
permNodesM2M(mat)

Arguments

mat A square adjacency matrix for a graph.

Value

A square adjacency matrix for the new graph, subject to a random permutation of the edges or nodes.
