In some shells you may find it works better to use

 nohup R BATCH myscript.R &

so that you can log out without killing background jobs.  (The nohup
command name indicates that the program will not respond to the HUP or
"hangup" signal.)

I agree with Martin that it is a good idea to end such scripts with
if you do not want the workspace saved.  Another variation is to use
the --no-save flag.

 nohup R BATCH myscript.R --no-save &
