I'm not aware of any such implementation but there was a thread on this mailing list some time earlier where I proposed a relatively simple method to assess the significance of a particular community. Given that you work in R, you should have all the necessary statistical tools (e.g., the Mann-Whitney U test) to implement it: http://lists.gnu.org/archive/html/igraph-help/2012-06/msg00014.html > Chen -- do you mean edge.betweenness.community()? > I tried it but then R hangs (haven't tried letting run for a few hours > though). edge.betweenness.community() is slow so it isn't really useful for graphs that contain more than a few hundred vertices -- unless you have a day to spare or so :) I would probably try multilevel.community() and/or infomap.community(). There is a recent review of community detection algorithms that you might be interested in: http://arxiv.org/abs/0906.0612 Best, Tamas _______________________________________________ igraph-help mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/igraph-help
