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.
Doing help.search("SOM") in R gives
batchSOM(class) Self-Organizing Maps: Batch Algorithm
SOM(class) Self-Organizing Maps: Online Algorithm
somgrid(class) Plot SOM Fits
so you ought to have it in your (recent enough) version of R. The
"class"
package is part of the VR bundle, which is shipped with R.

This answer was no > availability. And no package dealing with SOM in CRAN.There are two SOM methods in package class (bundled with R) and a package som (formerly GeneSOM) on CRAN. -- Brian D.
