Install R from APK

[jimjam-slam]

Hey hey! Just wanted to leave a quick note that R is now distributed with APK (and installing it there means you don't need to mess with the compiler build flags required to build many CRAN packages):

RUN apk add R R-dev

I know this repo is pretty old now, just wanted to leave this here for other folks trying to get something going (in my case, a Home Assistant add-on, which requires Alpine Linux). I substituted this for the manual download and compilation of R.
