When we first wrote RTextTools, we opted to use RWeka for boosting and bagging algorithms for lack of a better alternative. We've discovered that this leads to all sorts of ugly rJava installation issues across platforms and prevents our users from getting started quickly. Recently, we've stumbled upon two excellent non-Java alternatives: LogitBoost in the caTools package, and the bagging implementation in the ipred package.

Consequently, we've eliminated RWeka from the list of dependencies and significantly streamlined the installation process. Windows users only need to deal with the Rtools installation now; developer Loren Collingwood left a helpful comment regarding Rtools in a previous post.
