Web4 dec. 2012 · igraph is a library for “complex network research”. While it integrates very well with R and provides a lot of convenient functions, huge graphs put a quick end to all the joy. The good news is: not all functions in igraph have bad performance. Some are actually amazingly fast – one just needs to avoid the bad ones. WebThen we can input those into the erdos.renyi.game function provided by igraph to generate a network of the same size and density, but with edges that are random re-arranged. random_graph <- erdos.renyi.game ( n = net59_n, p.or.m = net59_density, directed = TRUE ) # where n is the number of nodes, p.or.m is the probability of drawing an edge, directed …
