You should read the vignettes for the package at: http://cran.r-project.org/src/contrib/Descriptions/caret.html these have the details for caret. There are many other methods. Typing help.search("confusion") yields four different implementations on my system. Looking at your email, you need to read something about basic predict methods. Please read ?predict.NaiveBayes Max ______________________________________________ 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.
