ERROR

Error in eval(predvars, data, env): object 'STATE_UT' not found

Answer 1

Well, the error message is telling you that that there is no column named STATE_UT in Training nor is there a object in the global environment called STATE_UT

colnames(Training)

will tell you what columns are in the Training object and

ls()

will tell you what objects are available in the global environment
