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 to support a two-rate model.
Thus I would like to know how we could simulate trait evolution for the
continuous trait with rates differing depending on the state of the discreet
trait.
Any suggestions are greatly appreciated.
Best wishes,
Alejandro
