[R-sig-phylo] ancestral reconstruction of geographic origin (function ace{ape})

Hello, I'm trying to reconstruct the major biogeographic region from which different families have originated. I have data on the proportion of each family's range that falls within each biogeographic region, as well as (of course) a phylogeny. My approach so far has been to assign, if

Re: [R-sig-phylo] Editing names of DNAbin object

Hi Wade, If I understood your problem correctly, maybe the example below will help you. library(ape) foo - vector(list, 2) foo[[1]] - ATACTACTATATT foo[[2]] - ATTTCCATTATGT names(foo) - c(seq1, seq2) foo - as.DNAbin(foo) names(foo) [1] seq1 seq2 names(foo) - c(SeqA, SeqB) names(foo) [1]

[R-sig-phylo] selecting terminal branch lengths?

Dear All I am trying to find a way to get a vector of only the terminal branch length for species in a phylogeny, but cant seem to find a way any suggestions? Best, Maria Mercedes -- Maria Mercedes Gavilanez Department of Biological Sciences 107 Life Sciences Building Louisiana State

Re: [R-sig-phylo] selecting terminal branch lengths?

Try this: # given an object of class phylo called tree # 1. create vector for terminal edge lengths terminal.edges-matrix(NA,length(tree$tip.label)); # 2. copy terminal branches into vector terminal.edges-tree$edge.length[tree$edge[1:(2*length(tree$tip.label)-2),2]=length(tree$tip.label)];
