KNN one factor predicting problem
...lease?
> cl<-as.factor(traindata[,13])
> knn(traindata[1:295,2], newdata[1:32,2], cl,k=2,
prob=TRUE)
Error in knn(traindata[1:295, 2], newdata[1:32, 2],
cl, k = m, prob = TRUE) :
Dims of test and train differ
Both traindata and newdata have 13 elements. Only one
of the first 12 elemnets is needed to predict the 13
element.
What's the problem of following commands?
Thank you very much indeed
