Because there is so much of a buzz around the R programming language in the data science and analytics world, in health-care and other domains, I wrote a book on R-programming for data analysis. The book aims to teach data analysis using R within a single day to anyone who already knows some programming in any other language. The book has sample code (which can be downloaded as a zip file from the Dropbox link provided in the text of the book) that uses the freely available, CMS-sourced Medicare Physician and Other Supplier Data CY 2014 health-care data-set which was released to the public a few years back and created quite a stir.
