title: How does RStudio save and export files?
body: <p>I'm new to RStudio.
  So far I managed to import my data from a csv file and write some code in order to manipulate it abit.</p>
  
  <p>Now, I want to do the following things:</p>
  
  <ol>
  <li><p>Save my whole project so that later I can pick it as is.</p></li>
  <li><p>Export the dataframe (marked in blue) back to csv so I can open it in another program.</p></li>
  </ol>
  
  <p>I'm trying to find how to do these in the RStudio GUI without writing a code for that. Tried fiddling with the same icons (marked in black) but none made sense to me. What is the difference between the left and right save icon?</p>
  
  <p>All the guides I'v seen relay on code only. Can someone explain in a human language how can I accomplish my two goals? </p>
