\name{crmatrix}
\alias{crmatrix}
%- Also NEED an `\alias' for EACH other topic documented here.
\title{Region-wise cluster membership}
\description{
Produces a matrix with clusters as rows and regions as columns,
indicating how many species present in a region belong to the clusters
}
\usage{
crmatrix(x,xc,percentages=FALSE)
}
%- maybe also `usage' for other objects documented here.
\arguments{
\item{x}{object of class \code{prab} as
generated by \code{prabinit}. Presence-absence data to be analyzed.}
\item{xc}{object of class \code{prabclust} or \code{comprabclust}
as generated by \code{prabclust} or \code{hprabclust}. The
clustering.}
\item{percentages}{logical. If \code{TRUE}, the output matrix will
give the proportion of species from a certain region in the cluster.}
}
\value{
A clusters time regions matrix as explained above.
