Hello, I am having a strange error; I did not see it before: I have a large graph gs: > summary(gs) Vertices: 15088 Edges: 993338 Directed: FALSE No graph attributes. Vertex attributes: name. No edge attributes. is.connected(gs) [1] TRUE I am calculating modularity: > mog.com<-fastgreedy.community(gs) > memb <- community.to.membership(gs, mog.com$merges, steps=which.max(mog.com$modularity)-1 ) > modularity(gs, memb$membership) [1] 0.4051626 and I want to get subgraph of module N3: $csize [1] 3620 7290 3767 85 60 19 5 7 4 3 9 7 8 8 3 6 7 3 3 3 3 4 4 6 4 5 6 2 3 5 4 4 3 7 [35] 4 4 4 2 3 2 3 5 4 2 3 3 3 3 3 3 2 4 3 2 3 3 2 3 2 2 2 2 2 2 2 2 2 2 [69] 2 2 2 2 2 2 2 2 2 > i<-3 > s<-subgraph(gs,V(gs)[ membership == (i-1) ]) Error in eval(expr, envir, enclos) : object 'membership' not found I do not understand the reason of this error message, what I am doing wrong? thank you best regards Galina is for the sole use of the intended recipient(s) and may contain confidential and privileged information.
