The original paper is here, with Matlab code. Others can tell you where this is in R. Ives, A. R., P. E. Midford, and T. Garland, Jr. 2007. Within-species variation and measurement error in phylogenetic comparative methods. Systematic Biology 56:252–270. Cheers, Ted On Wed, Aug 2, 2017 at 7:50

[R-sig-phylo] Phylogenetic quantile regression

2017-08-02 Thread briansedio
Hi Agus, Did you ever figure out a way to do phylogenetic quantile regression? I have searched and searched, and cannot find any tool or even literature on the topic. I would ideally like to make it work in R. Thanks for any update or information. Brian Sedio se...@si.edu

Hi (This is my first query to a group like this, so my apologies if the subject is a little basic) I have a data set of insect COI barcodes, that i've aligned and edited in MEGA. I've also generated the K2P distances in MEGA, producing a very large spreadsheet of intra and inter specific

[R-sig-phylo] phylogenetic signal with sample sizes but no standard errors

2017-08-02 Thread Vincenzo Ellis
Dear list users, I'm interested in testing for phylogenetic signal in a trait of parasites: the number of host species a parasite infects. I have a phylogeny for the parasites and I have tabulated the number of host species each parasite infects from the literature. However, some parasites are
