Re: [R-sig-phylo] phylogenetic circular linear regression
Hi, If your adventurous you could probably write your own model in R or Stan or similar. The wrapped Normal or the Von Mise distribution are circular and map from 0 to 2pi. My suggestion would be to include a species level phylogenetic "random effect" for the mean parameter to account for the autocorrelation. This is how the MCMCglmm package includes phylogeny. If you write it as sampling statements it might look like y ~ MV(mu, k) mu = a + bx + h h ~ MVN (Mu, Sigma) Hope that helps lead you on the right track.

Re: [R-sig-phylo] phylogenetic circular linear regression
Hi again Frank, I just realized that a sine or cosine transformation would leave you with opposite colors on the hue having the same value... probably not so handy. Sorry, that was a poor suggestion...

Re: [R-sig-phylo] phylogenetic circular linear regression
Hi Franz, I don't know about anything like what you propose but maybe you could sine-transform your trait and then use phylogenetic linear or logistic regression?
