R is a development environment for statistical data analysis, but that is not all. It is a free software, distributed under the GNU GPL licence. R is emerging worldwide as the most used software for statistical, econometrics, and financial analysis as well as a tool for predictive analysis and machine learning. R features a very active community and an abundance of freely available packages that implement the most varied features. In short, it is a tool that should definitely be part of a data scientist’s toolkit! The course wants to first provide an introduction to the R environment and language, and then to address some specific issues such as the input and output of data in various formats, statistical analysis, and charting for visual analysis of the data.
