title: R: Save all data.frames in workspace to separate .RData files
body: <p>I have several <code>data.frames</code> in an environment which I would like to save into separate .RData files. Is there a function which is able to save to whole workspace?</p>
  
  <p>I usually just do this with the following function:</p>
  
  <pre><code>save(x, file = "xy.RData")
  </code></pre>
  
  <p>but is there a way I could save all the data.frames separately at once?</p>
