 Hello
 
I have questions about gbm package.  It seems we have to devide data to two part (training set and test set) for first. 
 
1- trainig set for running of gbm function
2- test set for gbm.perf   
 
is it rigth? 
I have 123 sample that I devided 100 for trainig and 23 for test.
 
So, parameter of cv.folds in gbm function is for what?
 
Thanks alot
Azam
