On Linux you can type in the terminal (I guess the command will
work in Mac too):

tail -f myfile.Rout

Then you hit Ctrl+C to stop tail from following myfile.Rout.

Another option would be the use of screen (again, this is a *nix
solution that may be available to Mac too). With screen you can
run R interactively detach the session, logout, come back and
reattach the session. But it seems that "tail -f" is what you
really needs since the R script is finished and you just need to
run it.
