R help - Apr 2007 - distance method in kmeans

I am trying to cluster some binary data using k-means . As the regular
"kmeans" available from stats package in R does'nt provide the
option to change the distance method. I was wondering there is any package
available to specify type of distance measure to be used in k means clustering
in  R. Especially distances like "Jaccard" which is good for binary
data.
   
               Thanks chandra

You could try clustan graphics, cheap and awesome with plenty of 
preprocessing capabilities of matrices.

Given this is one of R's strengths (matrix programming) I would imagine 
there is code out there that would enable you to generate a matrix for use 
in k-means.

Typically, what I would do is to generate a set of tetrachoric correlations 
if I am going to use binary data in k-means

Chandra,

you might want to have a look at package "flexclust".

Best,
Bettina
