You can use a Kolmogorov-Smirnov test for that, as outlined here:

There is also a plain C implementation of their method which will eventually be 
integrated with igraph (once I find time for it). Currently it is a separate 
project, but it works from the command line, so you can simply call out from R 
to this implementation if you want to do batch processing:

(Instructions: download, cmake, make, make install).
