\alias{m.weight}
\title{Computes a weigth matrix from a \code{\linkS4class{metabarcoding.data}}}
\usage{
m.weight(data)
}
\arguments{
\item{data}{a \code{\linkS4class{metabarcoding.data}} instance}
}
\value{
a weight matrix usable for M statistics
}
\description{
The weight can be considered as a propability of presence of a MOTU in a 
given sample. This function defines this probability as the fraction of
the maximal occurrence frequency over all samples.
}
\examples{
data(termes)
termes.ok = termes[,colSums(termes$reads)>0]
w = m.weight(termes.ok)
