[R] How to obtain the unique communities when plotting VENNs?

[John Kane]

Hi Krissey,

I don't have an answer for you but here are some hints on how to ask questions on R-help.
http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example and http://adv-r.had.co.nz/Reproducibility.html

In particular we probably need your actual code and some sample data.  Use dput() see ?dput or read about it in the above links.
