title: RStudio - how to recover data after crash?
body: <p>Was calculating a massive amount of data that took two weeks to run.  When I was trying to export the data to use in MS SQL, my RStudio crashed and I had to reopen it.  Now when I try to look for the data it seems to be missing!!! YIKES!</p>
  
  <p>Is that data sitting in a file somewhere or does all data you were working with in that session disappear?</p>
  
  <p>Sorry for my ignorance of R.  I'm pretty new to it.</p>
  
  <p>Thanks in advance for any help.</p>
