Advanced methods

The EnQuireR package provides several functions in order to study the data set from a multivariate point of view:

• The function ENMCA() to perform a Hierarchical Classification and a Multiple Correspondence Analysis on the individuals of the data set

• The functions ENlisib() and ENdensity() to give a better readability of the outputs of the MCA

• The function ENellipse() to draw confidence ellipses around the categories of a chosen variable

• The functions ENmarking() to do a semantic marking of the clusters obtained with ENMCA() and its graphical representation GRmarking()
