R is an open-source programming language designed for statistical computing, data analysis, and machine learning. It provides built-in statistical functions, powerful data visualization capabilities, and access to thousands of packages from the Comprehensive R Archive Network (CRAN). RStudio Server is a web-based integrated development environment (IDE) that enables you to write, debug, and run R code from any device through a browser interface.

In this article, you will install R from the CRAN official repository on Ubuntu 24.04, set up RStudio Server for remote access, secure the installation, and create user accounts for collaborative work.

Prerequisites

Before you begin, you need to:

• Have access to an Ubuntu 24.04-based server as a non-root user with sudo privileges.
• Configure a domain A record pointing to your server's IP address (for example, rstudio.example.com).

Install R from CRAN Official Repository

The Comprehensive R Archive Network (CRAN) is the central repository for R packages, versions, and documentation. Installing R from CRAN ensures you have the latest stable release with active community support. In this section, you add the CRAN repository to your system and install R.

1. Update the server's package index.

   console Copy

   $ sudo apt update
   

   Explain Code

2. Install the required packages for adding external repositories.

   console Copy

   $ sudo apt install --no-install-recommends software-properties-common dirmngr -y
   

   Explain Code
   • software-properties-common: Enables adding external repositories to Ubuntu's trusted sources.
   • dirmngr: Verifies the authenticity of software from external repositories.

3. Download and add CRAN's GPG key to Ubuntu's trusted key directory.

   console Copy

   $ wget -qO- https://cloud.r-project.org/bin/linux/ubuntu/marutter_pubkey.asc | sudo tee /etc/apt/trusted.gpg.d/cran_ubuntu_key.asc
   

   Explain Code

4. Verify the GPG key fingerprint.

   console Copy

   $ gpg --show-keys /etc/apt/trusted.gpg.d/cran_ubuntu_key.asc
   

   Explain Code

   Output:

   pub   rsa2048 2010-10-19 [SCA] [expires: 2027-09-30]
         E298A3A825C0D65DFD57CBB651716619E084DAB9
   uid                      Michael Rutter <marutter@gmail.com>
   sub   rsa2048 2010-10-19 [E] [expires: 2027-09-30]

   The fingerprint E298A3A825C0D65DFD57CBB651716619E084DAB9 confirms the authenticity of CRAN's official GPG key.

5. Add the CRAN repository to the server's sources list.

   console Copy

   $ sudo add-apt-repository "deb https://cloud.r-project.org/bin/linux/ubuntu $(lsb_release -cs)-cran40/"
   

   Explain Code

   Press Enter when prompted to confirm the addition.
