The unreleased 0.6 version of igraph has a much faster implementation
for this, you can download a nightly build source R package from here:
https://code.google.com/p/igraph/downloads/list
Make sure that you download the right file, there are C, Python
packages there as well. I can send you a windows binary package, if
you are using windows.
Note that in this version vertices and edges are numbered from one and
not from zero, so you might need to update your code.
Best Regards,
Gabor
