Se presenta el paquete de R FactoClass, donde se implementa la estrategia descrita en Lebart et al. (1995), que combina métodos factoriales con análisis de conglomerados, en la exploración multivariada de tablas de datos. Se utilizan funciones de ade4 (Chessel et al. 2004) para realizar el análisis factorial de los datos y de stats para el análisis de conglomerados. Se crean funciones para tareas específicas y se modifican algunas de las existentes. Se describen los pasos para crear FactoClass en ambiente Windows y se ilustra el uso del paquete con un ejemplo.
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.
