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:

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:
