R is an open-source, free environment and programming language that is primarily utilized to analyze data and perform statistical calculations. This language offers various graphical and statistical methodologies that comprises classical statistical tests, time series analysis, and linear/non-linear modeling. R language also supports a lot of user-generated packages for specific areas of interest. That’s another reason why the R language is more applicable to multiple fields.
This blog will demonstrate the method to install the R language in Ubuntu 22.04. So, let’s start!
Installing R programming language on Ubuntu 22.04
For the purpose of R programming language installation on Ubuntu 22.04, follow the below-given instructions.
Step 1: Update and Upgrade the Ubuntu 22.04
To update and upgrade packages on Ubuntu 22.04, firstly, open up the terminal by pressing “CTRL+ALT+T” and execute the following command:

Step 4: Import GPG key
Next, import the GPG key in your system through below command:
$ wget -O- https://cloud.r-project.org/bin/linux/ubuntu/marutter_pubkey.asc | sudo gpg --dearmor | sudo tee /usr/share/keyrings/cran.gpg
Step 5: Add CRAN repository
After importing the GPG key, you need to add the CRAN repository that is highly recommended for R installation:
$ echo deb [signed-by=/usr/share/keyrings/cran.gpg] https://cloud.r-project.org/bin/linux/ubuntu $(lsb_release -cs)-cran40/ | sudo tee /etc/apt/sources.list.d/cran.list
Once the repository is imported, refresh the APT repository list by using the update command:
$ sudo apt update
Step 6: Install R through CRAN repository
Now, your Ubuntu 22.04 system is ready to install the R language from the CRAN repository. To do so, type the following command:
$ sudo apt install r-base
Now “R” exists on our Ubuntu 22.04 system.
Step 7: Check R version
After installing the R language on Ubuntu 22.04, verify its existence by checking the build version:
$ R --version
The below-given output signifies that we have successfully installed R version “4.2.0” on our system:
Step 8: Run R
Next, run the R environment first by using “R” command in the terminal:
$ sudo R
After executing the “R” command, the R environment will be activated in the current terminal. You can also separately activate and use the R environment by searching it manually in the “Applications” menu:
Step 9: Terminate R
After using the R language, you want to terminate the activated shell environment. To do so,use the “q()” command and press “y” from your keyboard:
