Ornstein-Uhlenbeck methods for comparative phylogenetic hypotheses

Description

The ouch package provides facilities for phylogenetic comparative analysis based on Ornstein-Uhlenbeck models of trait evolution along a phylogeny. Multivariate data and complex adaptive hypotheses are supported.

Classes

The basic class, ouchtree, is provided to encode a phylogenetic tree. Plot and print methods are provided.

The class browntree derives from class ouchtree and encodes the results of fitting a Brownian Motion model to data.

The class hansentree derives from class ouchtree and encodes the results of fitting a Hansen model to data.
