title: Saving workspace image, in R
body: <p>When closing R Studio at the end of a R session, I am asked via a dialog box: "Save workspace image to [working directory] ?"</p>
  
  <p>What does that mean? If I choose to save the workspace image, where is it saved? I always choose not to save the workspace image, are there any disadvantages to save it? </p>
  
  <p>I looked at stackoverflow but did not find posts explaining what does the question mean? I only find a question about how to disable the prompt (with no simple answers...): <a href="https://stackoverflow.com/questions/4996090/how-to-disable-save-workspace-image-prompt-in-r">How to disable &quot;Save workspace image?&quot; prompt in R?</a></p>
