PARDO, CAMPO ELÍAS  and  DEL CAMPO, PEDRO CÉSAR. Combination of Factorial Methods and Cluster Analysis in R: The Package FactoClass. Rev.Colomb.Estad. [online]. 2007, vol.30, n.2, pp.231-245. ISSN 0120-1751.

The new R package FactoClass to combine factorial methods and cluster analysis is presented. This package is implemented in order to perform a multivariate exploration of a data table according to Lebart et al. (1995). We use some ade4 functions (Chessel et al. 2004) to perform the factorial analysis of the data and some stats functions in R to perform cluster methods. Some new functions are programmed to make specific tasks and another old ones are modified. We describe the implementation of FactoClass in the Windows environment and illustrate its use with an example.
