Yes, I've been trying to use Rob's method. However I can't see how it
allows incorporation of the other variables (communism, religion) I
want as they are categorical/factors. How would you go about including
these?
I am interested in trying the lnam function. However I
Hi
look also for motmot and auteur packages

Hi Roland,
There are two functions for Rob's method to combine phylogenetic and spatial
signal, although both - as far as I can tell - are based on gls methods, one
uses independent contrasts, and thus I'm not sure if it is set up in such a way
to allow you to include factors in the model.
Dear all, I tried to test something similar to Jason, but relating the
change in rates to the acquisition of a trait, instead to a specific date.
For that, I used a phylogeny with ten taxa, without outgroup.
I used exactly the same script gently proposed by Liam but got the
following error
Hi Agus.
It looks like in your example the Hessian matrix of partial second
derivatives (the curvature) at the optimum is numerically singular. I'm
not sure what this means - it could be that the surface is very flat, or
alternatively that it is highly correlated.
Is the error fatal, or do
