I think you'll find the caret package, along with its vignettes, very helpful:

http://cran.r-project.org/web/packages/caret/index.html

If you google for "caret machine learning" you'll find many useful
links. For instance:

* The JSS Publication:
http://www.jstatsoft.org/v28/i05/paper

* Slides from a presentation of caret:
