mat2UndirG {GraphAT} | R Documentation |
A function to turn an adjacency matrix for a graph into a graphNEL object.
mat2UndirG(V, mat)
V |
A vector of node names |
mat |
A square symmetric matrix indicating the presence of edges |
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.
A graphNEL object.
