com <- cbind(V(g),e$membership) #V(g) gets the number of vertices
com <- cbind(V(g)$name,e$membership) #To get names if your vertices are labeled
It work perfectly for small community but it stops without any error after Two hours for large communities (more than 150 million relations) with no error dans nos result.
What is the problem ? Is igraph not adapted for huge community ?
Thanks
