Hi all
I receive this error message: Error in mymodel$MSE : $ operator is invalid
for atomic vectors
When I use KNN.
This is the code:
library(e1071)
train <- rbind(iris3[,,1], iris3[,,2], iris3[,,3])
cl <- factor(c(rep("s",50), rep("c",50), rep("v",50)))
knn.cv(train, cl, k = 3, prob = TRUE)
sqrt(mymodel$MSE)
#error message : Error in mymodel$MSE : $ operator is invalid for atomic
vectors
thanks,
Nancy
