Hi Everyone,
I'm working on testing the effects of a likelihood reweighting algorithm
that I think will improve the use of morphometrics in phylogenetic
analyses. To do that, I need to do a bunch of tree searches using
simulated data. I'm using a modified form of the tree search script in the
P
Hi Everyone,
I'm measuring phylogenetic signal in a morphometric dataset using Pagel's
Lambda and Blomberg's K. I tend to think of both of these as continuous
values, but in reviewing the literature I've noticed that most authors
treat phylogenetic signal as either there or not. The way that th
Hi all,
I've been investigating the use of Pagel's lambda and run into a problem
comparing trees that have a low speciation rate and no extinction with
trees that have a high speciation rate and lots of extinction. I'm
comparing phylogenetic signal in two characters. In the first, I simulate
a
Hi everyone,
I was wondering if anyone knows a good R function or package for doing a
maximum likelihood search for a phylogenetic tree using continuous
characters. I'm aware of Rcontml, but I'm looking for something that I can
change and modify the individual steps in the search process rather
