If the network is in edge list format and there is a third column is treated as an edge attribute with the name of the column
readNetwork( fileName, filePath = NULL, fhead = TRUE, skipColumn = 1, edgeListFormat = 1 )
fileName |
vector of fileNames with the networks |
filePath |
path of the files NULL by default |
