Downloading R and RStudio (2024)

Downloading R and RStudio

If you plan to use R, you will need to download R and install it on your computer. It is also advised that you download and install RStudio. RStudio will make it easier to use R and manage your R scripts.

Two good things about R, are that it is free and it runs on most computers.

You can download R from: https://www.r-project.org/

What is CRAN and why is that a good thing? When you try to download R from the R Project website, you will have to pick a CRAN site to get your download of R. CRAN stands for the “Comprehensive R Archive Network” (CRAN), which is a collection of sites carrying identical material, consisting of the R distribution(s), the contributed extensions, documentation for R, and binaries.

The CRAN master site is at WU (Wirtschaftsuniversität Wien) in Austria and is mirrored daily to many other CRAN sites around the world. Please use the CRAN site closest to you to reduce network load.

From CRAN, you can obtain the latest official release of R, daily snapshots of R (copies of the current source trees), as gzipped and bzipped tar files, a wealth of additional contributed code, as well as pre-built binaries for various operating systems (Linux, Mac OS Classic, OS X, and MS Windows). CRAN also provides access to documentation on R, existing mailing lists and the R Bug Tracking system.

Downloading R You can download R from: https://www.r-project.org/. Simply click on the CRAN link under Download in the list on the left side of the main R site. You can then pick from the list of worldwide CRAN sites for your download. There is a CRAN server at Washington University, St. Louis, MO, USA. That would be a good option. Clicking on the cran.wustl.edu link will take you to the actual download page.
