Sure.

Look at the Dockerfile (== "recipe", like shell) for the r-base container.

  https://github.com/rocker-org/rocker/blob/master/r-base/Dockerfile

Starts from vanilla Debian testing, and installs R. Takes no time, is fully
automated and has been running that way for years.  You can build up from
there, my blog has examples, as have many many other sites by other people.


One other recent-ish example is the r-apt Rocker image. Sets the repo for
current R (based on builds that Michael Rutter looks after based on my
official Debian package), then adds info for the PPAs Michael looks after and
you got over 4,000 CRAN packages ready to install as binaries -- just like
that.  The link is for 'disco' aka 19.04, we have the others too (but I need
to add 19.10 now).

  https://github.com/rocker-org/rocker/blob/master/r-apt/disco/Dockerfile

Both meet free *and* simple. And you don't have to build either. Just 'docker
pull'. There is more at the Rocker Project for you.
