  1. Update the package index:
    $ sudo apt update
    
    Ubuntu repository contains stable version R packages. However, optionally if you wish to install the latest GNU R version add the official R-Project repository:
    $ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9
    $ sudo add-apt-repository 'deb https://cloud.r-project.org/bin/linux/ubuntu eoan-cran35/'
    
  2. Install R:
    $ sudo apt install r-base
    
  3. confirm the R installation by checking its version:
    $ R --version
    
  4. Start using R:
    $ R
    
  5. (optional) Install RStudio, the integrated development environment for R.
    DID YOU KNOW?
    Ubuntu repository contains approximately 860 ready to install and use stable library R packages. This means that in most cases you do not need to install and compile R library from source using R shell. In fact this is not recommended at all! All you need is to install an appropriate r-cran package by using the apt command. See bellow.
    To install additional libraries using apt command, first search the package index for available packages. For example let's see if the R library ggplot2 is available:
    $ apt-cache search r-cran | grep ggplot2
    r-cran-cowplot - GNU R streamlined plot theme and plot annotations for 'ggplot2'
    r-cran-egg - GNU R extensions for 'ggplot2': custom geom, custom themes, plot
    r-cran-ggally - GNU R extension to r-cran-ggplot2
    r-cran-ggdendro - GNU R create dendrograms and tree diagrams using 'ggplot2'
    r-cran-ggforce - accelerating GNU R ggplot2
    r-cran-ggplot2 - implementation of the Grammar of Graphics
    r-cran-ggridges - Ridgeline Plots in 'ggplot2'
    r-cran-ggthemes - extra themes, scales and geoms for r-cran-ggplot2
    
    To install the actual R library package enter:
    $ sudo apt install r-cran-ggplot2
    
  6. Test the library installation by loading it from R shell:
    $ R
    > library(ggplot2)
