Re: [R-sig-phylo] dating cladograms in R

Dear Nicolai, I don’t have branch lengths, just the topology. Is there a way to estimate a posteriori the branch-lengths using molecular data for most, but not all species? In any way, I was aware of chronos function but I haven’t seen it used in the literature and wondered if there was any

Re: [R-sig-phylo] dating cladograms in R

Dear Fabio, you might also use the chronos function in ape, which demands a data frame with calibrations (if you have information from published trees that could be use to calibrate your tree; cf. email from Joe), and which assumes that you have a phylogenetic tree whose branch lengths are in

Fabio you might have luck with Brian O'Meara's datelife: https://github.com/phylotastic/datelife Essentially it grabs dates from published trees and applies it to your own. Brian can provide more details. (^_<)〜☆ HTH. JWB
