Datasets for Machine Learning With R by Lantz

I recently read Machine Learning with R by Brett Lantz. This is a book that provides an introduction to machine learning using R. I really enjoyed the book and thought Lantz did an excellent job explaining the content as well as providing many good references and examples, which is what lead to my problem with the book. As far as I can tell, Packt Publishing does not make its datasets available online unless you buy the book and create a user account which can be a problem if you are checking the book out from the library or borrowing the book from a friend. All of these datasets are in the public domain but simply needed some cleaning up and recoding to match the format in the book so I went ahead and made a github repo to host them.
