I have 2 questions;
1. I would like to plot this graph & the overlapping communities in the same
manner as the examples given in cohesive.blocks. How ?

You can use the mark.groups argument of plot.igraph, see the docs.

2. if there are 3 communities, then there are 8 possible classes;
A,B,C,AB,BC,AC,ABC, & none. So is there a method to index the different
vertices according to the classes, as in the typical igraph community
membership functions?

I am not sure what exactly you want. Can you give a simple example?

Maybe you want

apply(mat, 1, function(x) paste(LETTERS[as.logical(x)],collapse=""))

Untested, 'mat' is your matrix.

Thanks!
