Overlapping parameters "k" in different functions in "ipred"
Dear List,
I have a question regarding "ipred" package. Under 10-fold cv, for different knn ( = 1,3,...25), I am getting same misclassification errors:
#############################################
library(ipred)
data(iris)
cv.k = 10 ## 10-fold cross-validation
bwpredict.knn <- function(object, newdata) predict.ipredknn(object, newdata, type="class")
for (i in seq(1,25,2)){
set.seed(19)
a<-errorest(Species ~ ., data=iris, model=ipredknn, estimator="cv", est.para=control.errorest(k=cv.k), predict=bwpredict.knn, nk = i)$err
print(a)
}
