machine learning libraries in s+ (or R)?

have been searching aro开发者_StackOverflow社区und the internet and stackoverflow, but haven't been able to find any information on libraries for machine learning in s-plus or R. does anyone know of any or could perhaps point me in the right direction? thank you!

You should probably start at the CRAN Task View on Machine Learning & Statistical Learning which covers the R side.

this one maybe helpful:machine learning open source software Filter by Programming Language

If your interest in ML on R includes classification and regression algorithms, then you will want to explore CARET. Be advised that, in a recent evaluation, I found the R offerings quite underwhelming when compared to the other ML OSS.
