[R] Adjacency Matrix help
I have created an adjacency matrix but have not been able to figure something out. I need to put zeros on the diagonal of the adjacency matrix. For instance, location (i,i) to equal 0. Please help.

Re: [R] Adjacency Matrix help
Thanks so much for your quick reply. it seems to work. the problem is that it now places actual zeros on the diagonal whereas the rest of the adjacency matrix has dots to represent zeroes. Do you have any ideas on how to change these zeros to dots like in the rest of the adj matrix? Or is it the same thing? Thanks. -- View this message in context: http://r.789695.n4.nabble.com/Adjacency-Matrix-help-tp3740946p3740996.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
