[R] what to use for sna/graphs?

[Sam Steingold]

What do people use for SNA/graph analysis in R?
So far I have been using igraph (it implements the Louvain community
detection algorithm as multilevel.community, which is the killer feature
for me).
However, igraph is severely lacking in visualization, which I also need.
graphviz & gephi are alleged to be good at visualization, but,
apparently, not so for analysis (specifically, community detection).
Also, it appears that there is no way to directly interface R to gephi
(apparently I am supposed to save graphs into csv and read them into
gephi separately), and the Rgraphviz package must be installed in a
quite unorthodox way (source("http://bioconductor.org/biocLite.R");
biocLite("Rgraphviz")); and then it is not clear how to turn an IGRAPH
graph object into an Ragraph object which Rgraphviz can handle.

So, what/how do people use/recommend?
Thanks!
