Dear all, I just read this paper: Revell, L. J. (2009). Size‐correction and principal components for interspecific comparative studies. Evolution, 63(12), 3258-3268. There is no coding for R, but it says it can be made using APE. >From what I could understand this is as simples as:
->bm.gls<-gls(trait~Bodymass, correlation=BM,data=DF,weights=varFixed(~vf)) ->residuals(bm.gls) Is this correct? Or do I need to ask for some special kind of residuals?
