How to do K means cluster analysis in R?
K-means algorithm requires users to specify the number of cluster to generate. The R function kmeans() [stats package] can be used to compute k-means algorithm. The simplified format is kmeans(x, centers), where “x” is the data and centers is the number of clusters to be produced.How to do k-means clustering step by step?
k -means++ algorithm is known to be a smart, careful initialization technique. It is originally intended to return a set of k points as initial centers though it can still be used as a rough clustering algorithm by assigning points to the nearest points.
