Yes, but not in the background:

repeat {
   f()
   Sys.sleep(300)
}

If you want it run in the background, get your OS to run R to do it.  
(It's possible the tcltk package will give you access to some tcl way to 
set a background process; I don't know.  Similarly, you could call out 
to C and start up another thread, etc., but R itself is single-threaded.)
