GBM implements boosted trees. It works for 0/1 outcomes, count outcomes,
continuous outcomes and a few others. You do not need to combine rpart
and gbm. You're best bet is to just load the package and run a demo
>demo(bernoulli).

HI, Dear Greg,

I AM A NEW to GBM package. Can boosting decision tree be implemented in
'gbm' package?   Or 'gbm' can only be used for regression?

IF can, DO I need to combine the rpart and gbm command?

Thanks so much!
