explicit

Constructs a KMeans algorithm object.

Parameters

[in]	distance	(optional) K-Means distance measure: "sqeuclidean" (default), "cityblock" , "cosine", "correlation", "hamming".
[in]	start	(optional) Cluster initialization: "sample" (default), "uniform", "cluster".
[in]	replicates	(optional) Number of K-Means replicates, which are generated. Best is returned.
[in]	emptyact	(optional) What happens if a cluster wents empty: "error" (default), "drop", "singleton".
[in]	online	(optional) If centroids should be updated during iterations: true (default), false.
[in]	maxit	(optional) maximal number of iterations per replicate; 100 by default.

Parameters

[in]	X	Input data (rows = points; cols = p dimensional space).
[in]	kClusters	Number of k clusters.
[out]	idx	The cluster indeces to which cluster the input points belong to.
[out]	C	Cluster centroids k x p.
[out]	sumD	Summation of the distances to the centroid within one cluster.
[out]	D	Cluster distances to the centroid.
