Hello List,
I have found communities in my graph through the walktrap.community function.
Here's the result:
> mywalktrap
Graph community structure calculated with the walktrap algorithm
Number of communities (best split): 27
Modularity (best split): 0.8075689
Membership vector:

maybe I don't understand well the dendrogram structure, but when I call
as.dendrogram I obtain:
> as.dendrogram(mywalktrap)
'dendrogram' with 2 branches and 2 members total, at height 286
which is not really helpful once plotted...
Am I missing something?
thanks in advance for any help!
best,
simone
