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 Frantz _______________________________________________ R-sig-phylo mailing list - R-sig-phylo@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-phylo Searchable archive at http://www.mail-archive.com/r-sig-phylo@r-project.org/
