Conducts correlational D-test from stochastic mapping

Description

This function conducts the 'D-test' of Huelsenbeck et al. (2003).

Usage

Dtest(t1, t2, nsim=100, ...)

Arguments

t1

set of stochastic map trees (i.e., object of class "multiSimmap" for character 1. Note that t1 and t2 should be of the same length.

t2

set of stochastic map trees (i.e., object of class "multiSimmap" for character 2. Note that t1 and t2 should be of the same length.

nsim

number of simulations to use in the test.

...

arguments to be passed internally to make.simmap. Note that (for now) these must be the same for both t1 and t2 (that is to say, we are not able to assume different trait evolution models for each tree).

Details

Note that this function has been included without much testing, and so the user should be wary.

Value

An object of class "Dtest".
