Yes, in particular with the tcltk toolkit and its event loop.  I can't name
the command with which you would control the event loop, though.

If you want to keep it in R itself, just use something like 

   while(1) {
     Sys.sleep(24*60*60)	# sleep one day

with suitable code in those two do_my_* functions.
