[BioC] enquiry about errorest with model-knn

[Liu, Xin]

Dear all,

Can somebody give me a clue why I always get the following error?

errorest(Species ~ ., data = iris, model = knn, estimator = "cv")$err

Error in model(formula, data = folddata, ...) : 
        unused argument(s) (data ...)

Xin LIU
