Unlocking the Power of R on Ubuntu: Installation and Package Management

Installing R on Ubuntu

As a non-root user with sudo privileges and access to a computer with a minimum of 2GB RAM, installing R on Ubuntu 18.04 is a straightforward process. R is an open-source programming language designed for statistical computing and graphical representation.

It is widely used by statisticians and data miners worldwide.

Prerequisites

Before you can install R on Ubuntu, ensure that your system meets the minimum requirements for running R. The computer should have a minimum of 2GB RAM and enough disk space for installing R and any necessary packages.

You should also have a non-root user with sudo privileges. Root users should not execute R code due to security reasons.

Installing R on Ubuntu

R is available in the official Ubuntu 18.04 repositories. However, it’s recommended to install the latest stable version of R from the R Foundation website.

To install R, follow these steps:

1. Add the R CRAN repository for Ubuntu 18.04 to your system.

“`

$ sudo add-apt-repository ‘deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/’

“`

2. Add the R repository key for signing packages to your system.

“`

$ sudo apt-key adv –keyserver keyserver.ubuntu.com –recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9

“`

3. Update your system’s package index and install R.

“`

$ sudo apt update

$ sudo apt install r-base

“`

Adding CRAN repository for the latest stable version of R

The Comprehensive R Archive Network (CRAN) is a network of servers around the world that store R packages. To install the latest stable version of R packages, add the CRAN repository to your system by following these steps:

1.

Launch the R console by typing `R` in your terminal. 2.

In the R console, enter the following command to add the CRAN repository to your system:

“`

> options(repos = c(CRAN = “https://cloud.r-project.org”))

“`

3. To check if the repository has been added, run the following command:

“`

> getOption(“repos”)

“`

This will return the current repository list for your system.

Installing R Packages from CRAN

R packages are collections of functions and data sets that enhance the functionality of R. They are available from the Comprehensive R Archive Network (CRAN) and can be installed from within the R console.

To install R packages, follow these steps:

Importance of CRAN packages

R packages are essential for analyzing data and creating visualizations in R. They provide pre-written functions for common statistical analyses, data manipulation, and visualization tasks.

Some of the popular packages include ggplot2, dplyr, and tidyr. Installing packages from CRAN ensures that you have access to the latest versions and bug fixes.

Installing build-essential package for compiling R packages

Some R packages require compilation during installation. To compile packages on Ubuntu, you need to install the build-essential package.

This package contains the compiler and other necessary tools. To install build-essential, run the following command:

“`

$ sudo apt install build-essential

“`

Installing and using a sample package (stringr)

To install a package, launch the R console and enter the following command:

“`

> install.packages(“stringr”)

“`

This will download and install the package. Once installed, you can load the package and view its functions by entering the following commands:

“`

> library(stringr)

> help(stringr)

“`

To use the package functions, enter the package name followed by the function name and the required parameters.

For example, to count the occurrences of a pattern in a string, enter the following command:

“`

> str_count(“Hello, world!”, “o”)

“`

This will return the number of occurrences of the letter “o” in the string.
