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?
