Hi Lara,
4 of the 6 igraph community detection functions can handle weighted
networks (spin glass, fast greedy, label propagation, and walktrap). Go
to http://igraph.wikidot.com/community-detection-in-r for some example R
scripts for community detection.
Good luck,
Andrew

Hello fellow igraphers!
I just came across igraph (the R package) and am just getting started.
I have read the docs to find out how to import the data I have into igraph and
have chosen to put it in 'ncol' format and then just use read.graph() as
described here
[http://cneurocvs.rmki.kfki.hu/igraphbook/igraphbook-foreign.html].
Now I would like to attempt some form of community detection on this dataset
that would take into account the fact that edges are weighted and undirected.
Is there a particular method in igraph that is especially well-suited for such
this task? I have just started reading on the topic, but it seems that most
algorithms were conceived to deal with unweighted graphs.
Many thanks for any help!
