How to Install R on Debian 9

R is a fast growing open-source programming language and environment that specializes in statistical computing and graphical representation. It is supported by the R Foundation for Statistical Computing and mainly used by statisticians and data miners for developing statistical software and performing data analysis.

This tutorial will walk you through how to install R on a Debian 9 system.

Prerequisites

Ensure that you have met the following prerequisites before continuing with this tutorial:

Installing R on Debian

At the time of writing this article, the latest stable version of R is version 3.5. The R packages from the Debian repositories are often outdated so we’ll install R by adding the repository maintained by CRAN .

The following steps describe how to install the latest stable version of R on Debian 9:

  1. Install the dependencies necessary to add a new repository over HTTPS:

    sudo apt install dirmngr apt-transport-https ca-certificates software-properties-common gnupg2

  2. Enable the CRAN repository and add the CRAN GPG key to your system by running the following commands:

    sudo apt-key adv --keyserver keys.gnupg.net --recv-key 'E19F5F87128899B192B1A2C2AD5F960A256A04AF'sudo add-apt-repository 'deb https://cloud.r-project.org/bin/linux/debian stretch-cran35/'

  3. Once the repository is added, update the packages list and install the R package by typing:

    sudo apt updatesudo apt install r-base

  4. Verify the installation by running the following command which will print the R version:

    R --version
    R version 3.5.1 (2018-07-02) -- "Feather Spray"

Installing R Packages from CRAN

One of the main reasons why R is so popular is the wide array of packages available through the Comprehensive R Archive Network (CRAN).

If you already don’t have installed, install the build-essential package which contains the tools required for compiling R Packages.

sudo apt install build-essential

For demonstration purposes, we’ll install a package named stringr , which provides fast, correct implementations of common string manipulations.

When started as root the packages will be installed globally and available for all system users. If you start R without sudo, a personal library will be set up for your user.

Start by opening the R console as root:

sudo -i R
R version 3.5.1 (2018-07-02) -- "Feather Spray"

  Natural language support but running in an English locale

R is a collaborative project with many contributors.
Type 'contributors()' for more information and
'citation()' on how to cite R or R packages in publications.

Type 'demo()' for some demos, 'help()' for on-line help, or
'help.start()' for an HTML browser interface to help.
Type 'q()' to quit R.

>
All the following commands are executed within the R console.

To install the stringr package simply type:

install.packages("stringr")

Installation will take some time and once completed, load the library:

library(stringr)

Create a simple character vector named tutorial:

tutorial <- c("How", "to", "Install", "R", "on", "Debian", "9")

Run the following function which prints the length of a string:

str_length(tutorial)

[1] 3 2 7 1 2 6 1

You can find more R packages at Available CRAN Packages By Name and install them with install.packages().
