RTextTools - A Supervised LearningPackage for Text Classification

http://www.rtexttools.com/

The train_model() function takes each algorithm, one by one, to produce an object passable to classify_model().

A convenience train_models() function trains all models at once by passing in a vector of model requests. The syntax below demonstrates model creation for all nine algorithms:
