Hi again,I've recently ran the following code.c1 <- clusters(y)c1$membershiplayout <- layout.fruchterman.reingold(y)x <- (which(c1$csize) < 8 & (c1$csize)> 1)vertices <- which(c1$membership==x)plot(subg,layout=layout[vertices])When I do c1$csize, it tells me I should have 32 communities that fit that range in x.However, it only plots 4 vertices.Any ideas why???On Wed, Feb 4, 2015 at 6:46 PM, Benika H <address@hidden> wrote:It would still print the nodes outside that range. I think I just an error in my plot lines.Thanks for checking. Hopefully, this is the solution.Thanks everyone ,Benika HOn Wed, Feb 4, 2015 at 6:31 PM, Gábor Csárdi <address@hidden> wrote:What's wrong with my off list suggestion.
