\title{Test of Diversification-Shift With the Yule Process}
\description{
This function performs a test of shift in diversification rate using
probabilities from the Yule process.
}
\usage{
richness.yule.test(x, t)
}
\arguments{
\item{x}{a matrix or a data frame with at least two columns: the first
one gives the number of species in clades with a trait supposed to
increase or decrease diversification rate, and the second one the number of
species in the sister-clades without the trait. Each
row represents a pair of sister-clades.}
\item{t}{a numeric vector giving the divergence times of each pair of
clades in \code{x}.}
}
\value{
a data frame with the \eqn{\chi^2}{chi2}, the number of degrees of
freedom (= 1), and the \emph{P}-value.
