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.

Answer 1

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

Answer 2

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.
