title: How can I stop a running R command in linux other than with Ctrl + C?
body: <p>I'm running R in interactive mode under Linux and mistakenly typed in a command that takes forever to run. I usually stop it using <kbd>Ctrl</kbd> + <kbd>C</kbd>. But it doesn't work all the time. When it doesn't work, is there another way?</p>
  
  <p>I don't want to kill the R session to start over either.</p>
