I investigated R (the sna/network packages by Carter Butts, in particular)
for large graphs and ran into the problem you describe. I'm pretty sure
that Carter mentions somewhere in the documentation that there are
efficiency issues with large graphs. Perhaps there are other R packages
that handle large graphs, but for the time being I've been using the boost
graph library (http://www.boost.org/libs/graph/) which is definitely able
to handle large graphs but of course then one needs to work in
C++ and hand-code SNA routines, which is probably not what most people
want to do.
