I would like to employ the concept of structural balance which requires signed networks. So far I have been using mainly sna, network, statnet and bipartite R packages, nevertheless it seems that options for signed network analysis are rather limited. I would be especially interested in tools for clustering and blockmodeling of signed networks. (After googling I only found research which uses ERGM (statnet package) for testing of the structural balance hypothesis, nevertheless nothing on mentioned exploratory techniques). Is there R option for signed networks? If not, what other software I should look for?
You can run under R-programming which is free software.. then you can install waveslim to perform this network analysis..
Thank you for the suggestion. Meanwhile I found that this kind of analysis can be done in Pajek (http://pajek.imfm.si/doku.php?id=pajek) which is a free software as well.
Python has a bunch of network analysis libraries but I don't recall anything specifically for signed networks. You might be reinventing the wheel there though since you'd likely have to bootstrap a lot of code to get to where you want.
