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:
