2.2 Installing R with CRAN on Ubuntu
20241007
Quick Start
sudo apt install r-recommended
wget https://raw.githubusercontent.com/eddelbuettel/r2u/refs/heads/master/inst/scripts/add_cranapt_noble.sh
sudo bash add_cranapt_noble.shDetails
The comprehensive R archive network (CRAN) hosts over 5,000 R packages
available for any installation of R. For MacOS and Windows the
packages are available for direct installation. On GNU/Linux the
packages generally need to be built before they are installed. Either
way we use R’s install.packages() command to install any one of
these 5,000 packages.
We can utilise the advantages of a direct installation (no source download and build) with Debian packages that are already compiled and ready to run. Only a small subset of the CRAN packages are pre-compiled in this way in the default distributions of Linux.
Dirk Eddelbuettel has built a full archive of CRAN packages ready to
install on Ubuntu. All R packages can be installed as Debian packages
on Ubuntu with names like r-cran-janitor, etc. The github repository
for r2u provides the details.
Shell scripts are provided to setup your system to use R2U. For
example
add_cranapt_noble.sh
can be run as the admin user (root) on your Debian or Ubuntu computer
to set up the R2U repository. This command works out of the box for a
Ubuntu 24.04 LTS (named as noble). Support for other versions of
Ubuntu is available.
