title: How do you know RStudio is running?
body: <p>I have a quick, simple question -- how do you know <code>R</code> is running and it's not stopped?</p>
  
  <p>I am running an optimizer from the <code>GA</code> package and I assumed that the computational time would be enormous, but as I pushed the <code>GA</code> loop, <code>R</code> just seems like it's stopped, but no returning error though. </p>
  
  <p>As I open the task manager, I can see that it's using around 0% of CPU. The first column being the CPU and the second the storage.</p>

  <p>How do I know the process is still running and not freezed?</p>
  
  <p>Thank you!</p>
