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?
There's probably no way if Ctrl-C doesn't work.
You might be able to attach gdb to the process and see what's going on
in there, but that's not too likely to be successful.
Next time it would be a good idea to save results on a regular basis so
that you can restart from a more recent save point.
