I also tested it successfully:

    image=$(guix pack -f docker -S /opt/gnu/bin=bin r)
    docker load < $image
    id=$(docker images -q profile | tail -n 1)
    docker run --rm --tmpfs /tmp:rw,size=787448k,mode=1777 -ti $id 

This creates an image for R, loads it, starts (and eventually removes)
a container in which R runs.

For people who find this cumbersome: use containers with Guix instead.
Here’s how:

    guix environment --container --ad-hoc r -- R
