Well, it looks definitely a tree to me.
http://www.nabble.com/file/p22938299/sp_matrix.csv sp_matrix.csv I'd like it to look something like the image file also attached... http://www.nabble.com/file/p22938299/2006-08-27_MST.png 2006-08-27_MST.png Is there a different layout that would accomplish that? ?Or if not that exactly, one that would help make the results a little clearer?
I am not sure what you mean. Of course you can plot it using different layouts, e.g. with layout.reingold.tilford (after choosing the root vertex in some way) and then it looks like a usual tree plot, but why would that be any better? Unless there is some external information about the graph (e.g. spatial positions of the nodes, or a distinguished root vertex), the layout on the image is just as good as the others. Gabor
