Arguments

dataset

a dataframe

Y

first group of variable

X

second group of variable (to be crossed with the first one)

method

if "proba" : the colour depends on the p-values given by the hypergeometric law. If "mean" : the colour depends on the value of the contribution to the chi-square distance

print

a logical value. If TRUE, tables of the chi-square distance are printed with cells coloured according to the chosen threshold

Details

This function is useful when comparing categorical variables. If report=TRUE, a directory named "EnQuireR" is created in your working directory (which can be known thanks to the getwd() function). This directory contains the final pdf report and also the teX file used to produce it.
