How to Install R on Ubuntu 24

Installing R on Ubuntu 24.04 is a fundamental skill for anyone working with statistical computing, data analysis, or scientific research on Linux servers. R has become the gold standard for statistical analysis, machine learning, and data visualization across industries, making it essential for developers and sysadmins to know how to properly set it up. This guide walks you through multiple installation methods, from the basic Ubuntu repository approach to setting up the latest version from CRAN, plus troubleshooting the inevitable hiccups that come with dependency management and environment configuration.

Understanding R Installation Options on Ubuntu 24.04

Ubuntu 24.04 offers several pathways for installing R, each with distinct advantages and trade-offs. The default Ubuntu repositories typically contain a stable but potentially outdated version of R, while CRAN (Comprehensive R Archive Network) repositories provide the latest releases with cutting-edge features and bug fixes.

The main installation approaches include:

Ubuntu’s default APT repositories (easiest but potentially outdated)
CRAN official repositories (latest version with regular updates)
Source compilation (maximum control but complex)
Snap packages (containerized but with some limitations)

Method	R Version	Update Frequency	Complexity	Best For
Ubuntu APT	4.3.x (typically)	Ubuntu release cycle	Low	Quick setup, stable environments
CRAN Repository	Latest (4.4.x+)	Regular updates	Medium	Development, latest features
Source Compilation	Latest/Custom	Manual	High	Custom configurations, performance tuning
Snap Package	4.3.x+	Regular	Low	Isolated environments

Method 1: Installing R from Ubuntu Repositories

The simplest approach uses Ubuntu’s built-in package manager. This method works well for most users who need a stable R installation without the latest bleeding-edge features.

# Update package lists
sudo apt update

# Install R base package
sudo apt install r-base

# Install development tools (recommended for package compilation)
sudo apt install r-base-dev

# Verify installation
R --version

This installation typically includes R version 4.3.x on Ubuntu 24.04, which handles most statistical computing tasks effectively. The process also installs essential dependencies like gcc, g++, and gfortran compilers needed for building R packages from source.

Method 2: Installing Latest R from CRAN Repository

For access to the newest R features and improvements, adding the official CRAN repository ensures you get regular updates and the latest stable release.

# Install prerequisite packages
sudo apt update
sudo apt install software-properties-common dirmngr wget

# Add CRAN GPG key
wget -qO- https://cloud.r-project.org/bin/linux/ubuntu/marutter_pubkey.asc | sudo tee -a /etc/apt/trusted.gpg.d/cran_ubuntu_key.asc

# Add CRAN repository
echo "deb https://cloud.r-project.org/bin/linux/ubuntu noble-cran40/" | sudo tee -a /etc/apt/sources.list.d/cran-r.list

# Update package lists
sudo apt update

# Install R
sudo apt install r-base r-base-core r-recommended r-base-dev

# Verify installation
R --version

The CRAN repository setup provides automatic updates when new R versions release, typically every few months. This approach works particularly well for development environments where staying current with R’s evolution matters.

Essential R Package Management Setup

After installing R, configuring package management properly prevents common frustrations with library installations and permissions.

# Create user library directory
mkdir -p ~/R/x86_64-pc-linux-gnu-library/4.4

# Set up R environment file
echo 'R_LIBS_USER="~/R/x86_64-pc-linux-gnu-library/4.4"' >> ~/.Renviron

# Install essential system dependencies for popular R packages
sudo apt install libcurl4-openssl-dev libssl-dev libxml2-dev libcairo2-dev libxt-dev

# For spatial analysis packages
sudo apt install libgdal-dev libgeos-dev libproj-dev

# For database connectivity
sudo apt install libmariadb-dev libpq-dev unixodbc-dev

These system libraries prevent the common “compilation failed” errors when installing popular R packages like ggplot2, dplyr, sf, or database connectors.

Installing RStudio Server for Web-Based Development

RStudio Server transforms your Ubuntu server into a powerful web-based R development environment, perfect for remote work or team collaboration.

# Download RStudio Server (check for latest version)
wget https://download2.rstudio.org/server/jammy/amd64/rstudio-server-2024.04.2-764-amd64.deb

# Install RStudio Server
sudo dpkg -i rstudio-server-2024.04.2-764-amd64.deb

# Fix any dependency issues
sudo apt install -f

# Start and enable RStudio Server
sudo systemctl start rstudio-server
sudo systemctl enable rstudio-server

# Check status
sudo systemctl status rstudio-server

RStudio Server runs on port 8787 by default. Access it through your browser at http://your-server-ip:8787 using your Ubuntu user credentials. For VPS deployments, ensure your firewall allows traffic on port 8787.

Common Installation Issues and Troubleshooting

Several predictable issues can derail R installations, but most have straightforward solutions:

GPG Key Verification Failures:

# If CRAN repository key verification fails
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9

# Alternative key import method
curl -fsSL https://cloud.r-project.org/bin/linux/ubuntu/marutter_pubkey.asc | sudo gpg --dearmor -o /usr/share/keyrings/cran-archive-keyring.gpg

Package Compilation Errors:

# Install comprehensive build environment
sudo apt install build-essential gfortran libblas-dev liblapack-dev

# For packages requiring Java
sudo apt install default-jdk
sudo R CMD javareconf

Permission Issues with Package Installation:

# Check R library paths
R -e ".libPaths()"

# Fix ownership if needed
sudo chown -R $USER:$USER ~/R

# Configure R to use user library by default
echo 'options(repos = c(CRAN = "https://cloud.r-project.org/"))' >> ~/.Rprofile

Performance Optimization and Multi-Core Setup

R’s default single-threaded behavior can be enhanced through proper BLAS/LAPACK library configuration and parallel processing setup.

# Install optimized BLAS libraries
sudo apt install libopenblas-dev

# Check current BLAS configuration
sudo update-alternatives --config libblas.so.3-x86_64-linux-gnu

# Install parallel processing packages
R -e "install.packages(c('parallel', 'doParallel', 'foreach'))"

# Configure R for parallel processing
R -e "library(parallel); detectCores()"

For dedicated servers with multiple cores, enabling OpenBLAS can significantly accelerate matrix operations and linear algebra computations common in statistical analysis.

Real-World Use Cases and Integration Examples

R installations on Ubuntu servers typically serve several practical scenarios:

Automated Data Pipeline Server:

# Create automated R script execution
#!/bin/bash
# /usr/local/bin/r-analysis.sh

cd /home/analyst/projects
/usr/bin/Rscript --vanilla daily_analysis.R > /var/log/r-analysis.log 2>&1

# Add to crontab for daily execution
# 0 6 * * * /usr/local/bin/r-analysis.sh

Shiny Server for Interactive Applications:

# Install Shiny Server
sudo su - -c "R -e \"install.packages('shiny', repos='https://cran.rstudio.com/')\""

# Download and install Shiny Server
wget https://download3.rstudio.org/ubuntu-18.04/x86_64/shiny-server-1.5.20.1002-amd64.deb

sudo systemctl start shiny-server

Database Integration Setup:

# Install database connectivity packages
R -e "install.packages(c('DBI', 'RMySQL', 'RPostgreSQL', 'odbc'))"

# Test database connection
R -e "
library(DBI)
library(RMySQL)
con <- dbConnect(RMySQL::MySQL(), 
                 dbname = 'analytics', 
                 host = 'localhost',
                 user = 'r_user',
                 password = 'secure_password')
"

Security Considerations and Best Practices

R installations on production servers require attention to security, particularly when exposing services like RStudio Server or Shiny applications to networks.

Create dedicated R users with limited system privileges
Configure firewall rules for R-related services (ports 8787, 3838)
Use SSL/TLS certificates for RStudio Server in production environments
Regularly update R packages to patch security vulnerabilities
Implement proper authentication mechanisms for web-based R services

# Create dedicated R user
sudo adduser ruser --disabled-password --gecos "R Analysis User"

# Configure RStudio Server with SSL (production setup)
sudo nano /etc/rstudio/rserver.conf
# Add: ssl-enabled=1
# Add: ssl-certificate=/path/to/certificate.crt
# Add: ssl-certificate-key=/path/to/private.key

# Update R packages regularly
R -e "update.packages(ask = FALSE, checkBuilt = TRUE)"

The R ecosystem continues evolving rapidly, with new packages and capabilities emerging constantly. Understanding these installation fundamentals provides the foundation for leveraging R's full potential on Ubuntu servers, whether for data science workflows, statistical analysis, or interactive application development.
