Thank you David for clarify some important aspects of building a phylogenectic tree. I am sure that it is very important for people like me that don't have to much experience in this theme yet. Sincerely, Em dom, 5 de jul de 2015 às 14:52, David Bapst dwba...@gmail.com escreveu: Just to

Just to clarify for future users who stumble on Liam's solution for Lilian, the second block of code attaches the new tips to non-ultrametric trees at the same distance as the current tips at maximum distance from the root. If this is a time-scaled phylogeny and the tree's root depth is equal to

Hi Lilian. If your tree is ultrametric, which you can check using: is.ultrametric(tree) then when you attach a tip to a node or edge using bind.tip the length of the terminal edge leading to that tip will automatically be specified so that the tree remains ultrametric. If this is not the

Dear all, I have a time calibrated phylogeny and I need to insert some species on it. When I added those species with bind.tip function (phytools) the new phylogenetic tree doesn't have the calibration time. I tried to solve this problem in other packages such as APE and other programs like
