In DOMjudge(https://github.com/DOMjudge/domjudge)

Or
Is there any plan to add R language? :)

I'm not familiar with R , it seems having source and input mixed together, unless using file as input.
so the solution will take care of input and output as files: data.in / user.out
R solution for A+B problem

a<- scan("data.in",what=integer(),quiet=TRUE)
write.table(a[1]+a[2], file = "user.out", row.names = FALSE, col.names = FALSE)

1. update to latest version
   run make.sh in core and set OJ_CLIENT_INTERNAL=0 in etc/judge.conf
2. set $OJ_LANGMASK=4194224; in web/include/db_info.inc.php or calculated from https://pigeon-developer.github.io/hustoj-langmask/
3. uncomment the r-base install script in install/Dockerfile

#RUN     DEBIAN_FRONTEND=noninteractive apt-get -y install --no-install-recommends r-base

4. run docker.sh / podman.sh depends on your container choice
