## Install R

Package for the *current R 4.4.* release* are available for most stable Desktop releases of Ubuntu until their official end of life date. However, only the latest Long Term Support (LTS) release is fully supported.  As of May 1, 2024 the supported releases are 

- Noble Numbat (24.04, amd64 only),
- Jammy Jellyfish (22.04, amd64 only),
- Focal Fossa (20.04; LTS and amd64 only),
- Bionic Beaver (18.04; LTS), and 
- Xenial Xerus (16.04; LTS). 

Run these lines (if `root`, remove `sudo`) to tell Ubuntu about the R binaries at CRAN.  

```sh
# update indices
sudo apt update -qq
# install two helper packages we need
sudo apt install --no-install-recommends software-properties-common dirmngr
# add the signing key (by Michael Rutter) for these repos
# To verify key, run gpg --show-keys /etc/apt/trusted.gpg.d/cran_ubuntu_key.asc 
# Fingerprint: E298A3A825C0D65DFD57CBB651716619E084DAB9
wget -qO- https://cloud.r-project.org/bin/linux/ubuntu/marutter_pubkey.asc | sudo tee -a /etc/apt/trusted.gpg.d/cran_ubuntu_key.asc
# add the R 4.0 repo from CRAN -- adjust 'focal' to 'groovy' or 'bionic' as needed
sudo add-apt-repository "deb https://cloud.r-project.org/bin/linux/ubuntu $(lsb_release -cs)-cran40/"
```

Here we use `lsb_release -cs` to access which Ubuntu flavor you run: one of
"jammy", impish", "focal", "bionic", ...

Then run

```sh
sudo apt install --no-install-recommends r-base
```

to to install R and its dependencies.
