The windows binary is the exe file, in form R-x.x.x-win32.exe, where x denotes the actual version of the program. Regardless of the version the setup has the same steps.

- During the next step you can specify which parts of R you want to install. Choices are: User installation, Minimal user installation, Full installation and Custom installation. Notice the required space under the selection panel (varies between 20 and 66 MB). In case you are a beginner in R, choose the default User installation.

First of all, you have to download the bundle package for MacOS X, so go to . Stable release to-date is 3.1.2 "Pumpkin Helmet". Simply install the package you downloaded and three main components will be installed: R framework, Tcl/Tk support for GUI and R.app (main IDE with GUI).
