[edit] Matlab code for network ringplot
Doug --
Here's a ringplot.m (The "ring" polar-coordinate dendrograms) file. Sorry it isn't commented better. The key to its use is the "groups vector", which codes the dendrogram by looking for differences between the numbers. For instance, if in a given 8-node network I had groups = [2,1,4,7,12,11,13], then it first sorts the nodes by those numbers (1,2,4,7,17,16,15) and then starts at the leaves by merging the 1-2 and 15-16-17 into single groups, then merges 4 onto the 1-2 group, then 7 onto the 1-2-4 group, and finally merges everything at the trunk. The actual raw values of the differences between numbers don't matter, just the ordering of those differences.
Hope that helps! Let me know if I can help in some other way, even if it's just to say that I've been too cryptic so far about how to use it. If it hits the stage where you need to cite its use for some purpose, please just cite whichever paper where you saw the similar figures (I guess you said it was my paper with Mark, so that's the 2005 PNAS House committees paper, I guess).
