I am solving a rare event cum classification problem. I have come across a package called SMOTEBoost which oversamples the rare event and boost the results. But I'm not sure is that supported in R.

Could you please help me how can I use SMOTEBoost in R? Any examples?

There are two packages in R that should be able to use SMOTE to up sample the minority class:

  1. unbalanced package, and
  2. DMwR package

It doesn't seem like they provide the boosting that is described in the paper that you might be referring to. But it should be straightforward to sew in SMOTE with the idea of boosting using some base tree packages in R like rpart (for example).
