Section 1.1: Installing R
You might wish to install RStudio after you have installed R. RStudio is a development environment for R that
simplifies many programming tasks.
Windows only:
Visual Studio (starting from version 2015 Update 3) now features a development environment for R called R Tools,
that includes a live interpreter, IntelliSense, and a debugging module. If you choose this method, you won't have to
install R as specified in the following section.
For Windows
1. Go to the CRAN website, click on download R for Windows, and download the latest version of R.
2. Right-click the installer file and RUN as administrator.
3. Select the operational language for installation.
4. Follow the instructions for installation.
For OSX / macOS
Alternative 1
(0. Ensure XQuartz is installed )
1. Go to the CRAN website and download the latest version of R.
2. Open the disk image and run the installer.
3. Follow the instructions for installation.
This will install both R and the R-MacGUI. It will put the GUI in the /Applications/ Folder as R.app where it can either
be double-clicked or dragged to the Doc. When a new version is released, the (re)-installation process will overwrite
R.app but prior major versions of R will be maintained. The actual R code will be in the
/Library/Frameworks/R.Framework/Versions/ directory. Using R within RStudio is also possible and would be using
the same R code with a different GUI.
Alternative 2
1. Install homebrew (the missing package manager for macOS) by following the instructions on https://brew.sh/
2. brew install R
Those choosing the second method should be aware that the maintainer of the Mac fork advises against it, and will
not respond to questions about difficulties on the R-SIG-Mac Mailing List.
For Debian, Ubuntu and derivatives
You can get the version of R corresponding to your distro via apt-get. However, this version will frequently be quite
far behind the most recent version available on CRAN. You can add CRAN to your list of recognized "sources".
sudo apt-get install r-base
You can get a more recent version directly from CRAN by adding CRAN to your sources list. Follow the directions
from CRAN for more details. Note in particular the need to also execute this so that you can use
