RE: [MORPHMET] Multivariate PICs?

Sarah, As far as I am aware, MorphoJ estimates a set of PICs one dimension at a time. Thus, for a multivariate dataset of N species and p-trait dimensions, this will return a matrix of N-1 by p. Here, each of the N-1 rows (nodes of the bifurcating tree) contains a vector of PICs, one per

[MORPHMET] Multivariate PICs?

Hi all, Primarily, I'm wondering if there is a way to calculate phylogenetic independent contrasts on multivariate shape data in R. However if no R method exists, I know a method to do this is implemented in MorphoJ, and I could possibly code an analogous method in R but I'm unsure how the

[MORPHMET] Photos vs scan

Dear All, Greetings! I am going to start a project which deals with studying morphological variability between bivalves belonging to Donacidae and Mactridae. The morphological variability would mainly focus on shell shape, internal structures, palial sinus, etc. I already have
