%description
Gaussian mixture models, k-means, mini-batch-kmeans, k-medoids and
affinity propagation clustering with the option to plot, validate, predict
(new data) and estimate the optimal number of clusters. The package takes
advantage of 'RcppArmadillo' to speed up the computationally intensive
parts of the functions. For more information, see (i) "Clustering in an
Object-Oriented Environment" by Anja Struyf, Mia Hubert, Peter Rousseeuw
