%description
An implementation of methods related to sparse clustering and variable
importance in clustering. The package currently allows to perform sparse
k-means clustering with a group penalty, so that it automatically selects
groups of numerical features. It also allows to perform sparse clustering
and variable selection on mixed data (categorical and numerical features),
by preprocessing each categorical feature as a group of numerical
features. Several methods for visualizing and exploring the results are
also provided. M. Chavent, J. Lacaille, A. Mourer and M. Olteanu
