sim.ratebystate

tree

variance of the Brownian process of evolution for <code>x</code>.

sig2x

variance of the Brownian process of evolution for <code>y</code> when <code>x-min(x)==1</code> (for <code>logarithm=FALSE</code>) or <code>x==0</code> (for <code>logarithm=TRUE</code>).

sig2y

intercept and slope of the relationship between the value of <code>x</code> and the Brownian rate in <code>y</code>.

beta

optional arguments which include <code>method</code> (<code>"by.node"</code> or <code>"by.branch"</code> indicating whether to assume the rate varies as a function of the node state or the mean branch state); <code>plot</code>, a logical value indicating 

This function attempts to simulate two characters under a model in which the rate of evolution for the second (<code>y</code>) depends on the states for the first <code>x</code>. See <code><a href="/link/ratebystate?package=phytools&version=0.2-40" rd-options="" data-mini-rdoc="phytools::ratebystate">ratebystate</a></code> for more details.
