[R] Solving Classification problems in R

[Luca Cerone]

Dear all,
I would like some advices on R packages to solve classification problems.
I have tried to search among the Task views, but couldn't find anything.

Can somebody recommend me some packages?

Some of the features I am looking for:
- deal with multiple classes
- use customized cost functions
- perform features/predictors selection

Any hint would be greatly appreciated,
thanks a lot in advance for the help!
Cheers,
Luca
