Dear R-Users and Developers,
I want to calculate something like k-means clustering, but with 
ordinal data (Braun-Blanquet) to combine this classification 
technique with a NMDS-Ordination.
I found an algorithm especially developed for categorical data: 
k-modes (Huang 1998). Is there a function implemented in R which can 
calculate with this algorithm. I found a hint on a poster-abstract 
from Gero Szepannek, Uwe Ligges and Claus Weihs. There it is stated 
that the algorithm is implemented in their package klaR. But I cannot 
find anything about k-modes in the klaR-Tutorial.

Could you please help me.


Dear Kim,

well, maybe you start writing a message to the authors of that 
poster-abstract at first who might be able to help?
Since I am one of those: Where can I find this abstract or poster (at 
least in order to remind Gero who does no longer work at the 
university to finally implement the feature, if it is not yet there)?


Some news on this:

Gero never presented it in his talk at the useR!2008 and we all forgot 
that he announced it in his abstract. He is working for a bank these 
days and is going to send his code within a few days. Will take a look 
if it is easy to add the existing code to klaR then.



FYI: I got the code now, will try to incorporate it soon.

Best,
Uwe
