Thank you. I sure will.. /jm Date: Tue, 23 Apr 2013 08:41:30 -0400 From: [email protected] To: [email protected] Subject: Re: [igraph] I'm getting Different MST each time
Hi, that's an old version of igraph and an old version of R. Could you please update igraph (and if you want, R as well)? The most recent igraph version is 0.6.5-1. Thanks. G.

Please send some self-contained example that reproduces the problem, e.g. make up some toy data.

For some reason, I seem to get a different MST diagram (nodes in different order) each time I run it. For example, sometimes the primary tree node is say "Jon K.". Other times, it could be "Larry Z." Could any help with what I am doing wrong?
