Re: [R-sig-phylo] Boostrap and likelihood values on branches

Hi Klaus, I did exactly as Gwennaël did and got no value equal to 0. You are right about the bug in prop.clades (and it's fixed now), but in the present case, and I believe in general, this should have no incidence because postprocess.prop.part() is called inside boot.phylo() before calling p

Dear Gwennaël, first it seems there was a bug in the function prop.clades from ape introduced recently, results in many zeros of bootstrap values. This function needs to be replaced in the ape package: prop.clades <- function (phy, ..., part = NULL, rooted = FALSE) { if (is.null(part)) {

Dear all, I used a very raw 18S phylogeny of Craniates to introduce phylogeny to students, and I would like to estimate bootstrap or likelihood values for branches. Sorry for this long message, but I hope you can answer at least some of my questions. 1) For bootstrapping, I obtain "zero" valu
