In dunleavy005/phylomoments: Efficient Computations of Phylogenetic Stochastic Mapping Moments

phylomoments

This R package implements a simulation-free dynamic programming algorithm for calculating higher-order moments of stochastic mapping summaries on a phylogeny [3]. Utility functions related to simulation-based stochastic mapping [1] and first-order moments [2] are also provided.

Installation

First, install the devtools package (if it isn't already installed) using install.packages("devtools"). Check to make sure you have a working development environment by running devtools::has_devel(). If it returns TRUE, then your development environment is correctly set up; otherwise, you'll need to install additional tools. More information on this subject can be found at https://github.com/hadley/devtools. In addition, if you're using Mac OS X, you will need to run the following commands in the Terminal.

curl -O http://r.research.att.com/libs/gfortran-4.8.2-darwin13.tar.bz2
sudo tar fvxz gfortran-4.8.2-darwin13.tar.bz2 -C /

The phylomoments package can then be installed from GitHub using the install_github function.

library(devtools)
install_github("dunleavy005/phylomoments")

By default, vignettes are not included in the installation. To install the phylomoments package with vignettes, use install_github("dunleavy005/phylomoments", build_vignettes = TRUE). Note that installing phylomoments with vignettes is a little slower than installing the package without them.

Vignettes

We provide three vignettes that illustrate how to use the functions provided in this package.

1. Introductory Examples
2. Rate Variation Testing
3. Evolutionary Conservation Testing

You can access the phylomoments vignettes with browseVignettes("phylomoments").
