R help - Jan 2009 - problems with ace (ape-package)

Hi everyone

I am trying to reconstruct ancestral character states with R. I used the ace
function of the package ape. I have discrete characters and tried to use the
ER and ARD model.

The problem is, that I get negative lik$anc values. Does anybody by chance
have an idea what might be wrong?

Thanks in advance
