R is a popular open source programming language that specializes in statistical computing and graphics. It is widely used by statisticians for developing statistical software and performing data analysis. One of R’s strengths is that it is highly and easily extensible by allowing users to author and submit their own packages. The R community is known to be very active and is noted for continuously adding user-generated statistical packages for specific areas of study, which makes R applicable to many fields of study.

The “Comprehensive R Archive Network” (CRAN) is a collection of sites (called mirrors) which carry identical material, consisting of many R packages and the R distributions themselves. You can download R and many R packages from any of the CRAN mirrors, but we will use the RStudio mirror.

In this guide, we will learn how to set up R on a DigitalOcean Droplet running Ubuntu 14.04. If your Droplet is running a different operating system, most of the instructions will still apply, but you may need to modify some of the commands. Following this guide to completion should take about 10-15 minutes.


For this tutorial, you will need:

  • An Ubuntu 14.04 Droplet with at least 1 GB of RAM. All the commands in this tutorial should be run as a non-root user. If root access is required for the command, it will be preceded by sudo. Initial Server Setup with Ubuntu 14.04 explains how to add users and give them sudo access.

Step 1 — Setting Up APT

To install R, we’re going to use the APT (Advanced Packaging Tool) tool. It uses a special file that lists the sources of where packages should be downloaded from. That file is /etc/apt/sources.list. In order to get the most recent version of R, we need to add the correct repository to the list of sources by adding a line to the sources file. The exact line you need to add will vary depending on the exact Ubuntu version. For Ubuntu 14.04, run the following command to add the correct repository to /etc/apt/sources.list.

  1. sudo sh -c 'echo "deb http://cran.rstudio.com/bin/linux/ubuntu trusty/" >> /etc/apt/sources.list'

If you are running a different Ubuntu version, consult this document for the correct repository to add.

To authenticate packages downloaded using APT, we have to add a public key. The Ubuntu archives on CRAN are signed with a key with ID E298A3A825C0D65DFD57CBB651716619E084DAB9. Add this key to your system.

  1. gpg --keyserver keyserver.ubuntu.com --recv-key E298A3A825C0D65DFD57CBB651716619E084DAB9

Next we need to add the key to apt.

  1. gpg -a --export E298A3A825C0D65DFD57CBB651716619E084DAB9 | sudo apt-key add -

Step 2 — Installing R

Now that APT has been set up properly, we are ready to use it to install R.

First, we need to update the list of available packages since we updated the sources list.

  1. sudo apt-get update

Now we can install R. We use the -y flag to automatically answer Yes when asked if we are sure we want to download the package.

  1. sudo apt-get -y install r-base

At this point, you should have an installation of the latest R version on your Droplet. You can test this by running the R command.

  1. R

You should see output similar to the following.

R version 3.2.1 (2015-06-18) -- "World-Famous Astronaut"
Copyright (C) 2015 The R Foundation for Statistical Computing
Platform: x86_64-pc-linux-gnu (64-bit)

R is free software and comes with ABSOLUTELY NO WARRANTY.
You are welcome to redistribute it under certain conditions.
Type 'license()' or 'licence()' for distribution details.

  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.


You are now inside the R interactive shell and can run arbitrary R commands.

Quit R, and return to your Droplet with the q() function:

  1. q(save = "no")

Step 3 — Installing R Packages from CRAN

Now that R is installed on your Droplet, any user on the Droplet can use R. When R is installed, it automatically installs a number of default packages, but in order to do anything truly meaningful in R you will probably need to install extra packages. It is important to have at least 1 GB of RAM available in order to install many packages.

As mentioned previously, CRAN hosts not only R itself, but many R packages as well. To install new R packages that are hosted on CRAN, or to update existing ones, you use the install.packages() function in R. If you wanted to install package somepackage, you would open R and run the following R command.

# This is an example, do not run this

However, any package installed by a specific user in R will only be available to that user by default. For example, if user sammy installs somepackage, then user jessie will not be able to use somepackage until they install it as well.

It is possible to install an R package in a way that makes it available to all users on the Droplet by installing it as root. As an example, let’s install the shiny package, which is a very popular package used to create web applications from R code. One way to install the package as root would be to log in as root, run R, and run the install.packages() command. However, it’s recommended not to log in as root, so instead we can just run the R command as root. We’ll also specify the repos parameter so that the package is downloaded from the RStudio CRAN repository, the same one we used when downloading R itself.

  1. sudo su - -c "R -e \"install.packages('shiny', repos = 'http://cran.rstudio.com/')\""

By installing a package this way rather than opening R and running the install.packages() command, the shiny package is made available to all users on the Droplet.

Let’s verify that shiny was installed correctly by trying to load it. Start an R session.

  1. R

In R, try loading the shiny package.

  1. library(shiny)

Running the previous command should result in no errors. Now quit R.

  1. q(save = "no")

Step 4 — Installing devtools Package

While many R packages are hosted on CRAN and can be installed using the built-in install.packages() function, there are many more packages that are hosted on GitHub but are not on CRAN. To install R packages from GitHub, we need to use the devtools R package, so let’s install it.

The devtools R package requires three system packages to be installed on the Droplet, namely libcurl4-gnutls-dev, libxml2-dev, and libssl-devc. Install these three packages:

  1. sudo apt-get -y install libcurl4-gnutls-dev libxml2-dev libssl-dev

Now the devtools R package can be installed. Remember that we want to install it using the same method as described above, rather than install it within an R session, because devtools should be available to all users.

  1. sudo su - -c "R -e \"install.packages('devtools', repos='http://cran.rstudio.com/')\""

The above command to install devtools could take several minutes to complete.

Step 5 — Installing R Packages from GitHub

Now that we have devtools installed, we can install any R package that is on GitHub using the install_github() function. Just like with CRAN packages, when installing GitHub packages you need to run the command from the system shell to make the package available to all users. Let’s try installing the shinyjs GitHub package, which adds functionality to the shiny package. A GitHub package is defined by its author (daattali) and its name (shinyjs).

  1. sudo su - -c "R -e \"devtools::install_github('daattali/shinyjs')\""

Let’s verify that shinyjs was installed correctly by trying to load it. Start an R session.

  1. R

In R, try loading the shinyjs package.

  1. library(shinyjs)

Running the previous command could result in some messages, but no error messages. Now quit R.

  1. q(save = "no")

Next Steps

You now have a working R installation on your Droplet.

To learn more about R, visit the official R website, or try learning R hands-on and interactively with the swirl package.

Thanks Man!! It actually helped me!!

I think DigitalOcean resource should be offical Ubuntu software installer guide. Every installing tutorial that used on Ubuntu exists on DigitalOcean and telling is very good, clear, understandable. Thanks a lot again.

Hello Dean, thank you for this guide to take the absolute beginner from zero to a working install. I have a question for a global install problem on Ubuntu 14.04.5 (Trusty).

Using sudo su - -c "R -e \"install.packages('devtools', repos='http://cran.rstudio.com/')\"" or the slightly modified sudo su -l -c "/usr/bin/R -e \"install.packages('package-name', repos='https://cran.rstudio.com/')\"" I get: /usr/bin/R: line 8: uname: command not found followed by 16 instances of /usr/lib/R/bin/R: line 8: uname: command not found /usr/lib/R/bin/R: line 143: exec: sh: not found The package package-name’s components do get downloaded but never get properly installed, be it for devtools, for swirl or any other package I want to install for all users. The only warning/error messages I get are all mentioned here.
Installing them from CRAN in a local library for one user works flawlessly. Can you help with that ? Cheers, -ced

During install facing this error:

E: Failed to fetch http://archive.ubuntu.com/ubuntu/pool/main/g/gcc-4.8/libgcc-4.8-dev_4.8.4-2ubuntu1~14.04.3_amd64.deb Hash Sum mismatch

E: Failed to fetch http://archive.ubuntu.com/ubuntu/pool/main/g/gcc-4.8/gcc-4.8_4.8.4-2ubuntu1~14.04.3_amd64.deb Hash Sum mismatch

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

What can do I now ?

After Installing R, i tried to installed below statement. $ sudo apt-get -y install libcurl4-gnutls-dev libxml2-dev libssl-dev It displays the below error. " Reading package lists… Done Building dependency tree
Reading state information… Done E: Unable to locate package libcur14-gnutls-dev "

what should I do?
