Main Page - NESCent Informatics Wiki. Package snowfall. Computing phylogenetic signal. I have posted a new function to compute phylogenetic signal for continuous traits using two methods: the lambda method of Pagel (1999) and Blomberg et al. (2003)'s K-statistic.
Rich Glor already created a very helpful wiki page on how to do this in R using several different functions. My function, phylosig() (code here), should make this even easier. Computing phylogenetic signal across multiple trees. A user just inquired as to whether there was an easy way to compute phylogenetic signal across multiple trees (say, a set of trees sampled from the posterior distribution or a set of equally parsimonious trees).
In fact, this is quite easy. To illustrate this, I will first simulate a set of 10 trees, and then I will generate data on one of these. This is intended to replicate our typical data analysis pipeline in which we have multiple trees but one vector of phenotypic trait values for species. Diagnostics_v3.
