check.network-methods {NetPreProc}

Graph checking

Description

Method to check the characteristics of a graph. Check if its adjacency matrix is symmetric, if it has NA, NaN o Inf values, and some minimals statistics about nodes and edges.

Usage

check.network(W, name="Network matrix")

Arguments

W

an object representing the graph to be checked

name

a character vector that will be printed as heading

Value

It return a list of strings about the characteristics of the graph

Methods

signature(W = "graph")

an object of the virtual class graph (hence including objects of class graphAM and graphNEL from the package graph)

signature(W = "matrix")

a matrix representing the adjacency matrix of the graph

Examples

library(bionetdata);
data(DD.chem.data);
check.network(DD.chem.data);
W <- Prob.norm(DD.chem.data);
check.network(W, "prob. transition matrix");
WL <- Laplacian.norm(DD.chem.data);
check.network(WL, "Laplacian norm. matrix");

library(graph)
g1 = randomEGraph(LETTERS[1:15], edges = 40);
check.network(g1, "random graph");
