[R] distance method in kmeans

[paulandpen]

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
