RTextTools is a free, open source machine learning package for automatic text classification that makes it simple for both novice and advanced users to get started with supervised learning. The package includes nine algorithms for ensemble classification (svm, slda, boosting, bagging, random forests, glmnet, decision trees, neural networks, maximum entropy), comprehensive analytics, and thorough documentation. The beta release was unveiled at the The 4th Annual Conference of the Comparative Policy Agendas Project on June 24, 2011 in Catania, Italy. The full release is available on the installation page. The RTextTools repository is available via GitHub, and the help mailing list is on Google Groups.
