For anyone encountering this problem, it stems from having both the klaR and rda libraries loaded. rda gives this error message because its predict.rda is defined: function (object, x, y, xnew, prior, alpha, delta, type = c("class", "posterior", "nonzero"), trace = FALSE, ...) and if (missing(xnew)) { stop("A new data to predict must be supplied.") } unload the rda package: detach("package:rda", unload=TRUE) -- View this message in context: http://r.789695.n4.nabble.com/regularized-dfa-rda-Klar-problems-with-predictions-tp3327188p4710913.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
