Calculating trait disparity between sister species

Question

[modernsynthesis]

I have a phylogeny and 3-D morphometric data. I want to calculate trait disparity between sister taxa PC scores. Is there a function in R or R script that will do this?

Look at the geiger and dispRity packages. And please, do not cross-post, as it runs the risk of annoying people in both communities.

Take a look at fdis() from FD or functional.beta.pair() and functional.beta.multi() from betapart (R packages). With them you can calculate different functional diversity approximations.
