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

donnee	a data frame corresponding to a contingency table (quantitative data)
by.quali	a factor used to merge the data from different rows of the contingency table; by default NULL and each row is characterized
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 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.
