ERGMs in R
statnet, a collection of packages for R for fitting Exponential Random Graph Models (ERGM), issued a major update. First change is that the main package is now called
ergm. Secondly, a set of additional packages has been made available. Apart from package
network, that provides a class system for relational data on which
statnet relies, there are couple of new ones, for example
dynamicnetwork facilitating work with the SONIA visualizer of network dynamics, but also many more. And, last but not least, thirdly, (almost) all of them are now available on CRAN websites.
Another interesting news is the forthcoming special issue of Journal of Statistical Software which is going to be devoted to these new developments. Preliminary versions of the articles are already available on
statnet website. I especially welcome the paper by Carter Butts that throughly explains the functionality of the
network package that has been available already for some time, but scarce on-line documentation made the conscious use very difficult.
