Changes to batchSOM from 1.9.1 to 2.0.1
Has the algorithm used by batchSOM for hexagonal topology changed in some
way between R 1.9.1 and 2.0.1? In comparing between the two versions, I
get identical results for rectangular topology, but very different results
for hexagonal topology. (I tried to find release notes for the VR bundle
that might explain the changes, bu...

SOM library for R
Hi.
Three years ago, I've read the question of availability of SOM library for
R using Kohonen's SOM_PAK in this mailing-list. This answer was no
availability. And no package dealing with SOM in CRAN.
Is this situation same?
Could you tell me availability this library?
Best Regards.

clustering
Hi there,
Sorry for the double email. Does R have the packages for the following
clustering methods? And if it does, what the commands for them?
1. SOM (Self-organization map)
2. Graph partitioning:
3. Neural network
4. Probability Binning
Thank you very much!

Self-Organizing Map analysis
Dear list,
I read the SOM package manual but I don't understand how to perform (for
example) 1) the SOM analysis on Iris data 2) with a visualization similar to
that of figure 7 in

Any suggestion? Thanks in advance,
Gianandrea

Question on SOM and clustering
Hello everyone,
I'm new to this list, so let me introduce myself: my name is Jonck van
der Kogel and I am a graduate student at the Erasmus University of
Rotterdam. I am currently working on my thesis which is on the use of
artificial intelligence for large data-sets.
To do an analysis of a certain data-set I want to use Kohonen's SOM
algorithm. However, as I understand it, the SOM
