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)
