R is an open source programming language designed for statistical computing. It is freely available from The Comprehensive R Archive Network. RStudio is a free Integrated Development Environment that provides a more graphical interface for writing R programs. RStudio includes R. If you choose to use RStudio or the course you are taking requires it, then you do not need to separately download R itself.
