Let’s start!

But note: For the installation process

🔴 you will need root access to your computer! 🔴

Go to www.r-project.org

Direct your browser to the homepage of the R-project.

Click on the CRAN link

CRAN stands for Comprehensive R Archive Network

Choose a mirror location

Select the location nearest to you OR …
Choose 0-Cloud which is operated by RStudio and will redirect you automatically to the nearest server.

Select your operating system

I recommend to download the precompiled version whenever possible.

Some links to other resources

I am on a Mac, so I will choose Download R for macOS for these slides.
For other distributions see the following links for YouTube videos:
- Windows 7, Windows 10, Windows 11
- Linux Ubuntu: Oct. 2020, Sep. 2021, Oct. 2021,
Or search for another installation guide.

R for macOS

Select the installer package for your macOS version and hardware: Intel or M1 Mac.
For older operating systems: scroll down or click the “old” directory right top.

Mental note: XQuartz

Always re-install XQuartz when upgrading your macOS to a new major version.
We will therefore return later to this page.

Download the installer program

Save the installer on your hard disk.

Start und run the installer

There are three things to watch out.

You have to agree to the license.

Choose location

Select standard location (applications folder), e.g. click the “Install”-button.

Allow installation

Allow the installer to install the software.

Installation completed!

We can now go ahead and install RStudio.

Go to www.rstudio.com

Scroll the homepage down.
Be aware that colors and content of the homepage change regularly.

Look for the button …

… “Download Free Desktop IDE” (or similar).
IDE stands for Integrated Development Environment.

Rstudio Download Page

Scroll the page down until you see a row of buttons for free downloads or downloads to pay.

Choose RStudio Desktop Free

Click the button for a free “Download” of the RStudio Desktop Open Source Licence.

Download RStudio — Finally!

The page analysis your system requirements and recommends you already a version.
If this version is not the correct one, then choose from the installer section.

Mac: Download the image

On my Mac it wants to download an image to my hard disk.

Mac: Drag RStudio to the Applications Folder

After extracting the image you can drag the program into the applications folder.

Open RStudio …

and write a simple calculation in the console window. I wrote 2 + 2 <enter>,
If you got the correct result: VOILÀ - you succeeded!👏👍

Return to R for macOS page

Remember our mental note: We need to download XQuartz on a Mac installation.

Download XQuartz

After downloading XQuartz open the saved image.

Install XQuartz

Installing the XQuartz package is a standard process, with one exception…
