Hello,
I am receiving the below error and cant figure out the solution.
Please help.
Code : - fit <- train(training[,-1],
training[, 1],
method = 'knn',
tuneLength = 20,
trcontrol = trcontrol,
preProc = c("centre", "scale"))
Something is wrong; all the Accuracy metric values are missing:
Accuracy Kappa

Median : NA Median : NA
Mean :NaN Mean :NaN
3rd Qu.: NA 3rd Qu.: NA
Max. : NA Max. : NA
