Thanks all. But I was looking for "KMedian" algorithm and not the "KMedoids" algorithm. The wiki says, " Note that this algorithm is often confused with k-medoids, which finds the optimal medoid, not median, for each cluster. (A medoid is an actual point from the dataset; a median is the mathematical median calculated separately for each dimension.)"
Any package which does KMedian clustering algorthm? Many Thanks.

There is no unique definition of a multivariate median and therefore there is no unique definition of "k-medians", but pam/clara is one possible version of it. (Of course if you think of k-medians as defined in a specific paper, it may still be something slightly different.)
