[R-sig-phylo] Detecting non-Brownian trait evolution

Hello, I want to analyze whether the evolution of certain traits within a clade fits a niche-filling model. I've looked at GEIGER and the different tests offered within that package to analyze the tempo and mode of evolution of continuous traits. I also wanted to implement the Node height

Re: [R-sig-phylo] Error message in gls analyses

Thank you Emmanuel. I think it was indeed a problem with degrees of freedom, too many independent variables. Best wishes, Alejandro -Original Message- From: Emmanuel Paradis [mailto:[EMAIL PROTECTED] Sent: den 10 november 2008 09:09 To: Alejandro Gonzalez Voyer Cc: r-sig-phylo@r

variances - diagonal terms in the variance-covariance matrix - differ between the species), and thus you should consider whether such an assumption makes biological sense in your system. Cheers Alejandro ___ Dr Alejandro Gonzalez Voyer Laboratorio

. However, you should be careful as the method is sensitive to trait-state distribution. Cheers Alejandro ___ Dr Alejandro Gonzalez Voyer Laboratorio de Conducta Animal Instituto de Ecología Circuito Exterior S/N Ciudad Universitaria Universidad Nacional

Re: [R-sig-phylo] Question regarding PGLS in caper

add that if you do go down the route of comparing such models, you need to think carefully first whether the models actually make sense for the traits you are comparing. Cheers Alejandro ___ Dr Alejandro Gonzalez Voyer Investigador Titular B
