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 -- Steve Lianoglou Graduate Student: Computational Systems Biology | Memorial Sloan-Kettering Cancer Center | Weill Medical College of Cornell University Contact Info: http://cbio.mskcc.org/~lianos/contact ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
