[R] Interrupt R?

[Spencer Graves]

       How can one interrupt the following gracefully:


while(TRUE){
   Sys.sleep(1)
}


       In R2.11.1 under Emacs+ESS, some sequence of ctrl-g, ctrl-c 
eventually worked for me.  Under Rgui 2.11.1, the only way I've found 
was to kill R.


       Suggestions on something more graceful?


       Beyond this, what would you suggest to update a real-time report 
when new data arrives in a certain directory?  A generalization of the 
above works, but I'd like something more graceful.


       Thanks,
       Spencer Graves
