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.
Best wishes,
Uwe Ligges
