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: http://files.meetup.com/1542972/Max_caret_NYCPA.pdf HTH, -steve
