To understand the differences between elements of differents class, the planes factoriales are insufficient. It is necessary, therefore, to proceed to the classification of the individuals in the vectorial space of the first factors of the analysis. To decide the number of axes to using, Barbary (1996) proposed a procedure which consists of realizing the classification several times changing the number of axes and using as criterion the number of individuals of the class with major quantity of individuals. The analysis to interpreting is that one that originates the minor number of individuals in the majority class.
The function tableclass realizes the classification several times y it proposes a number of axes to the classification.
