(You can get both from http://www.r-project.org/; the sna package is under "contributed packages" on CRAN.) For information, (some) references, and examples, take a look at the help for the routines hdist(), sdmat(), structdist(), netlm(), and netlogit(). You might also be interested in gdist.plotdiff() and gdist.plotstats(), which are of use in visualizing various properties of graph sets (i.e., multiple networks).
