\name{descfreq}
\alias{descfreq}
\title{Description of frequencies}
\description{
Description of the rows of a contingency table or of groups of rows of a contingency table
}
\usage{
descfreq(donnee, by.quali = NULL, proba = 0.05)}
\arguments{
\item{donnee}{a data frame corresponding to a contingency table (quantitative data)}
\item{by.quali}{a factor used to merge the data from different rows of the contingency table; by default NULL and each row is characterized}
\item{proba}{the significance threshold considered to characterized the category (by default 0.05)}
}
\value{
Returns a list with the characterization of each rows or each group of the \code{by.quali}. A test corresponding to the hypergeometric distribution is performed and the probability to observe a more extreme value than the one observed is calculated. For each row (or category), each of the columns characterising the row are sorted in ascending order of p-value.
