Get metaweb

Computation of the binary metaweb from a list of graph

getMetaweb(gList)

Arguments

• gList: A list of graph objects of class igraph.

Details

This function computes the metaweb from a list of graph. It computes the union (in the sense of graph theory) of the set of graphs.

Returns

getMetaweb returns an object of class igraph.

Examples

# Generating a set of Erdos-Renyi graphs
library(igraph)
gList <- c()
for(i in 1:4){
  graphLocal <- erdos.renyi.game(60, type = 'gnp', p.or.m=0.1, directed=TRUE)
  V(graphLocal)$name <- as.character(1:60)
  gList <- c(gList, list(graphLocal))
}
names(gList) <- c("A","B","C","D")

## building the metaweb
graphMetaweb <- getMetaweb(gList)
