\name{Dtest}
\alias{Dtest}
\title{Conducts correlational D-test from stochastic mapping}
\usage{
Dtest(t1, t2, nsim=100, ...)
}
\arguments{
\item{t1}{set of stochastic map trees (i.e., object of class \code{"multiSimmap"} for character 1. Note that \code{t1} and \code{t2} should be of the same length.}
\item{t2}{set of stochastic map trees (i.e., object of class \code{"multiSimmap"} for character 2. Note that \code{t1} and \code{t2} should be of the same length.}
\item{nsim}{number of simulations to use in the test.}
\item{...}{arguments to be passed internally to \code{make.simmap}. Note that (for now) these must be the same for both \code{t1} and \code{t2} (that is to say, we are not able to assume different trait evolution models for each tree).}
}
\description{
This function conducts the 'D-test' of Huelsenbeck et al. (2003).
}
\details{
Note that this function has been included without much testing, and so the user should be wary.
}
\value{
An object of class \code{"Dtest"}.
