In addition to the ideas so far, there is also corHMM. https://rdrr.io/cran/corHMM/man/corHMM.html is the main help for this, but you can also use corHMM::ancRECON, corHMM:rayDISC, and corHMM:corDISC. corHMM::plotRECON can plot ancestral state reconstructions. For tip uncertainty, you can do

Dear Sim�n, Typically people do this by �painting� regimes on the tree using the discrete trait and then trying different OU models for the different regimes. For example, does being in the island regime lead to a higher rate of evolution (bigger sigma in the BMS model) than being in the

Re: [R-sig-phylo] units of sigsq

(log(g)^2)/MY: it�s about the accumulation of variance with time, and variance has units squared. And please don�t apologize for the question. You only have it because we as a field have been sloppy about not including units with our measurements in papers (I�m guilty of this, too). So it�s
