Hi Everybody,

i again have the problem in using tune.knn(), its giving an error saying missing values are not allowed.... again here is the script for BreastCancer Data,

library(e1071)
library(mda)

trdata<-data.frame(train,row.names=NULL) attach(trdata)

xtr <- subset(trdata, select = -Class)
ytr <- Class

bestpara <-tune.knn(xtr,ytr, k = 1:25, tunecontrol = tune.control(sampling = "cross"))

and here i got the mentioned error.

can anybody help me in this regard...

Thanks & Regards,
