Selection of k in k-means clustering based on Pham et al. paper ``Selection of k in k-means clustering''.
kselection allows to inject a function that provides a different implementation of kmeans algorithm. This feature has developed thanks Harold Pimentel.nstart is not a parameter of kselection to facilitate compatibility with different implementations of kmeans algorithm.kselection allows the parallel execution of the algorithm using foreach package.traceoption in the kselection function shows a trace, the progres must be selected using the progressBar option.kselection function display a trace of the progress.kselection when the number of rows in the input data is lower than 15.
