evolvcv.lite

a phylogenetic tree in modified <code>"phylo"</code> format (see <code><a href="/link/read.simmap?package=phytools&version=0.2-40" rd-options="" data-mini-rdoc="phytools::read.simmap">read.simmap</a></code>).

tree

an <code>n</code> x <code>m</code> matrix of tip values for <code>m</code> continuously valued traits in <code>n</code> species - row names should be species names.

an optional integer value indicating the maximum number of iterations for optimization - may need to be increased for large trees.

maxit

tolerance value for <code>"L-BFGS-B"</code> optimization.

This function takes a modified <code>"phylo"</code> object with a mapped binary or multistate trait and data for two and only two continuously valued character.  It then fits four different evolutionary models: common rates and correlation; different rates, common correlation; different correlations, common rates; no common structure.

phylogenetics

maximum likelihood

comparative method

phytools provides various functions for phylogenetic
        analysis, mostly relevant to comparative biology.
