 ```***** To join INSNA, visit http://www.insna.org ***** Hi Andrej, You can also use "statnet" / "ergm" within R. For example, summary(net ~ triadcensus(0:15)) will give the counts of the 16 types for network "net". If your broader interest is in modeling then because "triadcensus" is a term in "ergm" you have great flexibility. For details see help("triadcensus") within "ergm".
