evolveTraits: Evolve two traits up a tree

Description

Given a phylogeny, will generate associated trait data for two traits following a Brownian motion evolution model.

Usage

evolveTraits(tree, sigma = 0.1)

Arguments

tree

A phylogeny.

sigma

The Brownian motion rate parameter.

Value

A list where the first object is a phylogeny with the desired number of species and the second object is a matrix of trait values for those species.

Details

Evolves two traits independently up phylogeny with Brownian motion evolution process. Sigma is currently set to 0.1 as default.
