title: Updated R, packages lost, what can I do?
body: <p>I updated R on Windows from version 3.2 to 3.4 and lost my packages. Now that I know this happens, I have found instructions on how to avoid this problem, but it's too late. </p>
  
  <p>Is there any way to recover my old packages (wherever they are and whatever they were all called) and plug them back into the updated version of R?</p>
  
  <p>Help would be greatly appreciated!</p>
