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.
Regards,
Shubha.

Subject: Re: [R] KMedians clustering in R
pam/clara in package cluster are probably as close to it as you can be.
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.)
