When using the function rfe I receive the warning
In x == y : longer object length is not a multiple of shorter object
length
more than 50 times.
I call rfe as follows:
nbProfile <- rfe(features.train.50pct, truth.train.50pct, sizes =
no.features, rfeControl = nbCtrl)
where
features.train.50pct data frame of 8 named columns, each of 487 rows,
numeric
truth.train.50pct factor of 487 logical elements
sizes 1, 2, ..., 8
nbCtrl rfeControl(functions = nbFuncs, method = "cv", verbose = F,
returnResamp = "final")
Does anybody know to which objects the warnings refer?
