Hi Alejandro.
If the discrete character is mapped on the tree in a "simmap" style,
then the student could use the phytools function sim.rates. Let me know
if you need more information.

Hello,
A student of mine is analyzing whether the rates of evolution of a continuous
trait depend on the state of a discrete trait. He finds no support for a model
with different rates of evolution. However, we would like to test how different
the rates would have to be in order for the method
