mat2UndirG: Change graph representations

In GraphAT: Graph Theoretic Association Tests

Description

A function to turn an adjacency matrix for a graph into a graphNEL object.

Usage

mat2UndirG(V, mat)

Arguments

V	A vector of node names
mat	A square symmetric matrix indicating the presence of edges

Details

mat is a square matrix with rows and columns corresponding to nodes in the graph. Entries of "0" indicate the lack of an edge. Since this is making an undirected graph, mat must be symmetric.

Value

A graphNEL object.
