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)
Well, since knn() can't handle incomplete data as it says, you can
choose to either omit incomplete observations (e.g., using na.omit()),
or to impute the data if the conditions are met (missingness at random,
...); see, e.g., packages cat, mix, norm, and e1071 for that.
HTH,
David
