Bash script to install R, and R package dependencies on Ubuntu 22.04.

#!/usr/bin/env bash

# This bash script contains the minimal proceedure required to install a base R
# environment on Ubuntu 22.04. It is used as a part of the Vagrantfile
# provisioning process for a brand-new, Ubuntu 22.04 virtual machine. This
# script may also be ran as a part of a standalone process to download R on any
# Ubuntu or Debian operating system.

set -o errexit   # abort on nonzero exitstatus
set -o nounset   # abort on unbound variable
set -o pipefail  # don't hide errors within pipes

# Before installation, begin with some basic sanity checks

# Bash Commands Reference:
#   apt-get: preferred for non-interactive/scripting over apt.
#   apt-get -qq: suppress all output except errors
#   apt-get --allow-unauthenticated: allow installation from user-added repositories
#   printf: a better, POSIX-compliant version of echo
#   Rscript -e: Runs R expression directly from bash
