Hi, I am analyzing lots of trees in which I need it to be ultrametric. I decided to use the function chronos, but in the middle of my run I got the following error message which I don't know the meaning:
Error in nlminb(start.para, f, g, control = opt.ctrl, lower = LOW, upper = UP) : NA/NaN gradient evaluation Someone has previously notice a similar error but I could not find a reply associated to the question (http://www.mail-archive.com/r-sig-phylo@r-project.org/msg03208.html) Thanks very much, Fabricia.
