Dear List, I have 2 data sets: one phylogenetic distance matrix, composed of 28 species of anuran amphibians, and a trait matrix composed of species by categories of visceral pigmentation on the surface of 20 organs [categories may vary from 0 (total absence of pigmentation) to 3 (surface of a given organ 100% pigmented), being the intermediary categories defined as follows: 1% > Category 1 < 50 % and 51% > Category 2 < 100%]. I want to test for a phylogenetic autocorrelation of these discrete traits. I was considering the analysis proposed by Pavoine et al. (2008) of the Abouheif/Moran test (adephylo::abouheif.moran), but I'm not sure if I can include categorical traits. Additionally, the adjusted Mantel for phylogenetic permutation proposed by Harmon & Glor (2010) seems also apropriated in this case. On the other hand, the method proposed by Pavoine et al. (2010) Ecol. Monog. allows for the decomposition of trait diversity along the tree nodes, but all the applications of this method I've seen were with continuous traits.
Any idea on how to solve this dilemma?
