How To Install R Language On CentOS 8

In this short article we will learn how to install R language on CentOS 8 operating system and try a simple code to run.


R is a powerful and open-source programming language and environment designed for statistical computing and data analysis. Developed by statisticians and data scientists, R has gained immense popularity in both academia and the business world due to its extensive libraries, data visualization capabilities, and a vibrant community of users and contributors. In this article, we’ll explore the key features, benefits, and applications of the R language.

Key Features of R

  • Statistical Analysis: R excels in statistical analysis and data manipulation. It provides a wide range of statistical techniques, including linear and nonlinear modeling, time-series analysis, hypothesis testing, and more.
  • Open Source: R is open-source software, which means it is freely available to anyone, and its source code can be modified and redistributed under the terms of the GNU General Public License (GPL).
  • Vast Library Ecosystem: R boasts a vast collection of user-contributed packages and libraries, which extend its functionality for various data analysis tasks. These packages cover topics such as machine learning, data visualization, and Bayesian statistics.
  • Data Visualization: R offers exceptional data visualization capabilities, with packages like ggplot2 that allow users to create complex and aesthetically pleasing plots and charts. Visualization is crucial for data exploration and presentation.
  • Data Manipulation: R provides powerful tools for data cleaning, transformation, and reshaping. The dplyr and tidyr packages are widely used for data manipulation tasks.
  • Integration: R can easily integrate with other programming languages like C, C++, and Python. This is particularly useful for incorporating specialized libraries or optimizing performance-critical code.
  • Reproducibility: R scripts and projects are highly reproducible, making it an excellent choice for research and data analysis where transparency and reproducibility are essential.
  • Community and Support: R has a large and active community of users and developers who contribute packages, documentation, and provide support through forums, mailing lists, and social media.

  • Machine Learning: R provides a growing ecosystem of machine learning packages, allowing users to build predictive models and perform data-driven decision-making.
  • Data Mining: R can be used for data mining tasks, including clustering, association rule mining, and text mining, through various packages.
  • Statistical Reporting: R facilitates the creation of statistical reports and documents using tools like R Markdown, allowing users to blend code, results, and narrative in a single document.

Applications of R

  • Academia and Research: R is extensively used in academic research across various disciplines, including economics, biology, and social sciences.
  • Data Science: R plays a pivotal role in data science projects, from data exploration and modeling to data visualization and reporting.
  • Finance: R is used for risk modeling, portfolio optimization, and financial analysis in the finance industry.
  • Healthcare: R is applied in medical research, epidemiology, and clinical trials analysis.
  • Business Intelligence: R helps businesses gain insights from data, make data-driven decisions, and improve operational efficiency.
  • Marketing and Advertising: R is employed for customer segmentation, campaign analysis, and market research.

How To Install R Language on CentOS 8 Operating System

In this sub chapter, we will learn how to install R language on CentOS 8 operating system. We hope this article will be helpful for anyone who seeks for R installation procedure. Here we go.

1. Enable the EPEL Repository
2. Update System Repository
3. Install R Language
4. Trying R Language

Before we are starting the installation process, there are some prerequisites which are to be met, as follow :

  • A running CentOS 8 system
  • A non-root sudo user with sudo privilege
  • Sufficient disk space

1. Enable the EPEL Repository

To enable the EPEL repository, open a terminal and run the following command:

$ sudo dnf install epel-release
$ sudo dnf config-manager --set-enabled PowerTools

2. Update System Repository

The next step is to update our system repository, by submitting command line:

$ sudo dnf update

3. Install R Language on CentOS

To install R language, we will submit the following command line :

$ sudo dnf install R

Output :

[ramans@bckinfo ~]$ sudo dnf install R
