Dear colleagues
I am struggling to find a way to remove phylogenetic signal from quantitative 
traits for a very large dataset (more than 5000 species. I already tried to 
implement a pPCA (function phyl.pca in the phytools package) but the function 
ran for more than a week and I decide to abort it. I also checked for the 
phylogenetic eigenvector approach but again I am not sure it makes senses for a 
so large phylogeny. (Too much PCoA axes and problem of selection of those 
axes). Thereofore, I would to ask if someone knows about a method to remove 
phylogeneitic signal for such large dataset, or, simply if it make sense to 
even try to remove phylo signal from such big data.

Many thanks
