How can I interrupt the current code in R using the keyboard command?

Question

Can anyone tell how can I abort a script run in R?

Let's say I have an infinite loop or some other problem, and I want to stop the script from starting. Is there a keyboard command that does this?

If this helps anyone, in Python it's Ctrl + c. I tried this in R and it didn't work :).

I was looking for this seemingly simple question, but could not find the answer.

Thanks in advance.

Answer 1

Self Answer (to a large extent a summary of other comments and answers):

• In RStudio , Esc works in windows, Mac, and ubuntu (and I would also suggest other Linux distributions).

• If the process is running, say the ubuntu shell (and this does not apply to R ), for example, using:

   Rscript my_file.R 

  Ctrl + c kills the process

  Ctrl + z pauses the process

• Inside the R shell, Ctrl + c kills help you avoid this.

Answer 2

Control-C works, although depending on what this process does, it may not be immediately accepted.

If you are using a unix-based system, one thing I do is control-z to return to the command prompt and then issue “kill” for the process id.

Answer 3

Try Ctrl + z But it will kill the process, not pause it.
