Installing R and RStudio with the Ubuntu default packages will leave you with strongly outdated versions. In practice, this often leads to version conflicts when installing additional R packages.
To avoid such conflicts, it does make sense to work with an up-to-date but not brandnew R version. As of now (summer 2020) I would recommend using v3.6, since most actively developed packages are working with it whereas support for v4 is often not yet provided.
Installing the right version of R requires that you know the Ubuntu code of your system. A lot of information on your system is stored in
$ cat /etc/os-release
Returns something like:
NAME="Linux Mint" VERSION="19.3 (Tricia)" ID=linuxmint ID_LIKE=ubuntu PRETTY_NAME="Linux Mint 19.3" VERSION_ID="19.3" HOME_URL="https://www.linuxmint.com/" SUPPORT_URL="https://forums.ubuntu.com/" BUG_REPORT_URL="http://linuxmint-troubleshooting-guide.readthedocs.io/en/latest/" PRIVACY_POLICY_URL="https://www.linuxmint.com/" VERSION_CODENAME=tricia UBUNTU_CODENAME=bionic
Relevant for the following is only the last line which could be assessed directly using e.g.
$ grep UBUNTU_CODENAME /etc/os-release UBUNTU_CODENAME=bionic
More information on Ubuntu releases: https://wiki.ubuntu.com/Releases.
In order to make sure that the R base will receive regular updates, it does make sense to install the package from a regularly updated repository. Knowing your Ubuntu code you can easily find and fitting deb link at RStudio’s Ubuntu ReadMe page at https://cran.rstudio.com/bin/linux/ubuntu/README.html.
For example, for the ‘bionic’ example system shown above and R v3.6 the adequate entry is
deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/ (cran35 is used for reasons of compatibility). This line must be added to
/etc/apt/sources.list to make sure its visited in system updates. You could use a text editor like nano, emacs or vi to do so (
sudo may be required) or simply append it through the command line:
$ echo "deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/" >> /etc/sources.list
To make sure the installation works, the correct SSL key has to be added to your system:
$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9
Now you can update the package library and upgrade existing files:
$ sudo apt-get update $ sudo apt-get upgrade
In case no previous R version was installed, you can do it now:
$ sudo apt-get install r-base-dev
$ sudo apt-get install libcurl4-openssl-dev libssl-dev libxml2-dev libudunits2-dev libgdal-dev cargo libfontconfig1-dev libcairo2-dev
RStudio provides its releases as DEB files. To install these, a tool like
gdebi must be installed on Ubuntu systems. In case you don’t have it, yet, it can be installed using:
$ sudo apt-get install gdebi
Find the right version for your system on the RStudio download page at https://rstudio.com/products/rstudio/download/#download and install it:
$ sudo gdebi /path/to/the/file/.deb
From time to time R packages will not work with the version of R you have installed. In case your R version is lower than required by the package, such issues can often be resolved by installing a previous release of the package. This can be achieved with ‘devtools’. To install ‘devtools’, go to the R console and do
Before getting started you need to find out which version of R you running and which version of the package will work with this. R has a builtin variable
version for this:
Finding out which version of the package should be used is a bit tougher. Navigate to the RDocumentation website at https://www.rdocumentation.org/ and find the relevant package there. Next to the name of the package, you will see the current version number and a button ‘Other versions’ next to it. At the bottom of the page, there is a section ‘Details’ with an entry ‘Depends’: this where you can see which R version the package requires. You may find out the latest version by selecting older versions from the dropdown on top of the page until you find a package version that supports your version of R.
Let’s, for example, say you are working on a machine with R version 3.1 and you want to install a compatible version of ggplot2. In this case, you will find that ggplot2 v.3.1.1 is the last version that supported R 3.1.
devtools you can now install this version of ggplot2:
require(devtools) install_version("ggplot2", version = "3.1.1")
