Clustering and bootstrap
Hi Eric, I work about bootstrap and clustering and I also write R-code about that, which is not documented up to now though. You may have a look at http://www.homepages.ucl.ac.uk/~ucakche/papers/classbrd.ps I also worked about species by site data and there is a parametric bootstrap test implemented as function prabtest in package prabclus. You may have a look at that, too. However, all of this does not really fit to your new question and I am not sure whether I have anything of interest to you. Feel free to contact me if you can somehow relate your problem to my work mentioned above. Best, Christian

Dear Listers, I emailed the list a few days ago about how to bootstrap a community matrix (species by sites) and get a consensus tree with node support. A friend pointed out that a similar question remained unanswered in 2004. I wish to re-word my question: is anyone aware of a package / method to obtain a majority-rule consensus tree from x distance matrices ? Is anyone using R to generate phylogenetic trees with node support ? thanks for your time and consideration, Eric P.
