SOM
Are you going to extend SOM? Namely, have you any plans to use hexagonal structure or to extend visualization (SOM_PAK-style-like)?

SOM_PAK is the package created by T.Kohonen. This package has a considerable quantity of options. I have got used to use SOM for research of data and this is the thing which most of all does not suffice me in RapidMiner.
RapidMiner uses rectangular grid. Sometimes hexagonal grid is better. The example can be seen here: http://en.wikipedia.org/wiki/Self-organizing_map (first plot of this article)/

Hi grinchukav,
I have found three som-related packages under "R", and this PDF mentioning them : http://www.google.com/url?sa=t&;rct=j&q=som_pak%2Br-cran&source=web&cd=6&ved=0CFQQFjAF&url=http%3A%2F%2Fr-kohonen.googlecode.com%2Fsvn-history%2Fr2%2Ftrunk%2Fkohonen%2Finst%2Fdoc%2Fkohonen-manual.pdf&ei=FSqpTvzAHcT0-gaa7bWvDw&usg=AFQjCNFhPHHZoGVfB26UxXCUgHFYFYVzkA
Since RapidMiner allows coding in "R" language, it would be useful to use them.
Would these packages answer your question ? Maybe a new operator called "RPackageLoader" under RM would useful ?
Cheers,
CP.

What do you mean by "hexagonal structure" and "SOM_PAK" ? I would be curious about it ;-)
