Estimnet for directed ERGMs is avalable from https://github.com/stivalaa/EstimNetDirected
The estimnet.so is the R library for estimation of undirected ERGMs. It is written in C and compiled with R CMD SHLIB.
The estimnet.so library and the working example of a network estimation may be downloaded from the links below.Download Estimnet for Mac

The library may be loaded by R command dyn.load("estimnet.so").
After it is loaded it may be used with R command .C("estimnet", "setting.txt", "Edge_List", "Attributes").
"setting.txt" is the config file, "Edge_List" and "Attributes" are names of network files:
"Edge_List" is the file with the list of network edges, and "Attributes" is the file with node attributes (when present).
that this version of code was tested on a network with about
100,000 nodes, but for such a large network it requiered large memory
(about 128 GB of RAM).
