How can I interrupt a running code in R with a keyboard command

Question

Can anyone tell how can I interrupt a running script in R    Let s say I have an infinite loop or some other problem  and I want to stop the script from running  Is there a keyboard command that does that   If it helps any  in Python it is Ctrl   c  I tried that in R  and it didn t work      I did some search for this seemingly simple question  but could not find the answer   Thanks in advance

Try out Ctrl   z But it will kill the process  not suspend it

I know this is old  but I ran into the same issue   I m on a Mac Ubuntu and switch back and forth   What I have found is that just sending a simple interrupt signal to the main R process does exactly what you re looking for   I ve ran scripts that went on for as long as 24 hours and the signal interrupt works very well   You should be able to run kill in terminal     kill -2 pid   You can find the pid by running    ps aux   grep exec R   Not sure about Windows since I m not ever on there  but I can t imagine there s not an option to do this as well in Command Prompt Task Manager  Hope this helps

Control-C works  although depending on what the process is doing it might not take right away   If you re on a unix based system  one thing I do is control-z to go back to the command line prompt and then issue a  kill  to the process ID

Self Answer  pretty much summary of other s comments and answers     In RStudio  Esc works  on windows  Mac  and ubuntu  and I would guess on other linux distributions as well   If the process is ran in say ubuntu shell  and this is not R specific   for example using   Rscript my file R   Ctrl   c kills the process  Ctrl   z suspends the process Within R shell  Ctrl   C kills helps you escape it
