Hi Jana, If your response variable is binary, I think you can use the binaryPGLMM function in "ape". For a multiple response I guess the formula should be like this: binaryPGLMM(Y ~ X1+X2, phy=phy, data=sim.dat)

Is it possible to use any kind of phylogenetically informed analysis in case of multiple regression (one response ~ multiple predictors) in case I assume binomial distribution of response variable? I try to explain species occurrence (proportional data) by a couple of species traits. I tried pgls function from "caper" R package, but I am not sure about it. Generally, it seems that there is not strong signal in my data, when I used lambda="ML" than lambda was set to zero.
