Multivariate Comparative Tools for Fitting Evolutionary Models to Morphometric Data

Fits multivariate (Brownian Motion, Early Burst, ACDC, Ornstein-Uhlenbeck and Shifts) models of continuous traits evolution on trees and time series. 'mvMORPH' also proposes high-dimensional multivariate comparative tools (linear models using Generalized Least Squares) based on penalized likelihood. See Clavel et al. (2015) and Clavel et al. (2018) .

mvMORPH: an R package for fitting multivariate evolutionary models to morphometric data

This package allows the fitting of multivariate evolutionary models (Ornstein-Uhlenbeck, Brownian motion, Early burst, Shift models) on species trees and time series. It also provides functions to compute log-likelihood of users specified models with fast methods (e.g., for Bayesian approaches or customized comparative methods), simulates correlated traits under various models, constrain various parts of multivariate models...

The package is designed to handle ultrametric and non-ultrametric trees (i.e. with fossil species) and missing data in multivariate datasets (NA values), SIMMAP mapping of discrete traits, measurement error, etc...

See the packages vignettes for details and examples: browseVignettes("mvMORPH").

mvMORPH 1.0.9

1. This is the version 1.0.9:

• Pruning algorithm to compute the determinant and matrix square root
• Some minor bugs corrections (see NEWS)

1. TODO:

• Incorporation of a tests-suite
• Implement the sampler (upcomming mvMORPH)
• Code improvements
• Extend the shift model to TS
• Formula option for independent variables
• Improved mvOU model
• Threshold model for categorical data

The current stable version of the mvMORPH package (1.0.8) is on the CRAN repository. https://cran.r-project.org/package=mvMORPH

Package Installation

You can install the package directly from gitHub through devtools:

library(devtools)

install_github("JClavel/mvMORPH", build_vignettes = TRUE)

(The installation may crash if your dependencies are not up to date. Note that you may also need to install Rtools to compile the C codes included in the package. For Windows and for Mac (and Tools )
