Dear R user,
I try randomForest and had an issue for the prediction. The training and test
data from two separate csv file. However I end with all NA or prediction.
Y is the continuouse variable, X variables are factors, continuous variables,
variables with numeric 0/1 indication Y/N (not coverted to factor), and
calendar year.
