Hello,

Is there any way to stop an R execution in a terminal where the previous 
command appears to have caused the code to hang? I basically need to get back 
to the prompt. 

Note that control-c doesn't restore the prompt and running top -o cpu from 
another terminal shows R at >99% CPU usage. While closing the terminal would 
work, I'd really like to save the data and the history file if I can. Is the 
temporary history list and/or variables from the current session located 
somewhere on my machine that I could get to and save before closing the 
terminal? Or is this a lost cause?

Thanks,
-Brian
