[R] Kohonen's SOM in R?

[John Aitchison]

Is there an implementation of the SOM ('Self Organizing Map') procedure in 
R ? 

I am aware of the implementations of Sammon mapping, multidimensional 
scaling and, somewhat peripherally, principal curves and projection 
pursuit ..  but not SOM per se as far as I can see. Am I missing 
something?


---------------------

for anyone interesed in SOM
I found Samuel Kaski's thesis "Data exploration using self-organizing 
maps" fairly accessible
http://www.cis.hut.fi/~sami/thesis.ps

and there is a wealth of material at
