script to compile R on macOS

compile_r.sh

#!/bin/bash

# R recommends setting this to avoid issues with programs like sed:
export LANG=C

# Get version in major.minor format:
VERSION=`sed 's/\([0-9]*.[0-9]*\).[0-9]*.*/\1/' VERSION`

# Use version-dev as default folder target:
TARGET=${1:-$VERSION-dev}


# Download recommended packages
