Hi,

for example to use the commuity membership of the karate (wckarate) (vertex community membership) to induce the subgraph of other graph ( here :karate3 ) which has some vertex or all the vertex of the first graph but connect differently   

sapply(sort(unique(membership(wckarate))), function(g) {

    subg1<-induced.subgraph(karate,which(membership(wckarate)==g)) })

You can do this, without problem. You need to be careful to match the vertices of the two graphs, but other than that, it is fine.

Hi,

I am not sure what you mean by "using" the membership vector.
