How To Install R Programming Language in Linux

R is a popular programming language and software environment used to build statistical and graphical computing tools for data science. It is in many ways similar to the S programming language and environment; R is a different implementation of S. Although there are some significant differences between the two.

R is free software available under the terms of the Free Software Foundation’s GNU General Public License. It is also cross-platform, it can be compiled and run on Linux, and other UNIX-based operating systems including FreeBSD and MacOS; and Windows as well.

R supports a variety of statistical (linear and nonlinear modeling, classical statistical tests, time-series analysis, classification, clustering, etc) and graphical techniques.

R Programming Language’s Key Features

Offers effective data handling and storage facility.
Provides a suite of operators for calculations on arrays, in particular matrices.
Ships with a large, coherent, integrated collection of intermediate tools for data analysis.
Offers graphical facilities for data analysis and display either on-screen or on hardcopy.
Provides conditionals, loops, user-defined recursive functions, and input and output facilities.
Allows users to add additional functionality by defining new functions.
It’s highly extensible via packages, about eight packages are supplied with the R distribution and many others are available through the CRAN (Comprehensive R Archive Network) family of Internet sites.
Supports for easily creating well-designed publication-quality plots such as mathematical symbols and formulae where needed, and.
Most S programs can run unaltered in R.
Also, for computationally-intensive tasks, C, C++, and Fortran code can be linked and called at run time.
Ships with comprehensive documentation, in LaTeX-like documentation format.

Verify R Installation in Linux

After installing the R packages, you can verify if the environment is set up well. To start the R program, run the R command which will launch the R program shell as shown in the next screenshot.

$ R

You can run a hello world program in R as shown:

>print("HelloWorld")
>print("HelloWorld", quote=FALSE)

To quit the R program shell, issue the q() command. You will be prompted whether you want to save the data from your R session, enter y for yes or n for no, or c to cancel:
