st: convert adjacency to edgelist
Hello Stata users,
I have a 438x438 adjacency matrix (symmetrical, non-directed) where the cells are the number of connections between each i,j pair (the pairs are members of congress and the connections are the number of caucuses each pair is in). I have it in Excel format, csv format, and Stata format. I also have it in Stata as a dyadic dataset with attribute variables (N=95,703). I want to convert either the dyadic data or the adjacency matrix to an edgelist that I could import into R (igraph) or NodeXL or TouchGraph so that I can make a network graph or two, but I need an edgelist to import into those programs. My goal is to make a network graph where I can show that party leaders are more central in the network than non-party leaders (two of my attributes are party leaders and centrality scores).
I'm wondering if I could write some Stata code that would allow me to convert one dataset or the other into an edgelist. But I don't know how to do that. Advice?
[Note: Perhaps I'd be better off trying to do this in R, but I'm much more comfortable in Stata than in R--I'm still quite a novice there. If some people on this list think this is easy to do in R and know how, I'm all ears and willing to work through it.]
Thanks!
