I'm not even sure what this question means, sorry.

Start screen on the linux system, then start R. Once the R job is
running, you can disconnect from the screen with Ctrl-A Ctrl-D and the
R job will continue in the background. Google linux screen for more
information.

Sure. Using screen you can have multiple sessions going.
