[R-sig-phylo] Generating all possible phylogenies...

Hello, Is it possible to use Ape Library to generate all possible evolutionary tree structures given a fixed number of nodes? We're studying plant leaf evolutions and we need to test each evolutionary tree on our models. We realize the number of trees would be huge, so we'd chooce only the

[R-sig-phylo] Finding distances between tree nodes

Hello, We're using the Ape library here in a plant shape research, and we need to find evolutionary time between two specific nodes on the evolutionary tree (by adding the branch lengths along from one node to another). I'd appreciate if anyone could hint the quickest way to do it. Thanks,
