Webgbm has two primary training functions - gbm::gbm and gbm::gbm.fit. The primary difference is that gbm::gbm uses the formula interface to specify your model whereas gbm::gbm.fit requires the separated x and y matrices. When working with many variables it is more efficient to use the matrix rather than formula interface.
