title: How do I split my x-axis into multiple plots in ggplot?
body: <p>I have the following dataset:</p>
  
  <pre><code>df &lt;- as.data.frame(cbind(Position = c(1,2,3,4,5,6,7,8,9,10), 
      Value = c(11.31, 10.39, 9.50, 6.61, 5.41, 
      3.88, 3.81, 1.25, 0.70,10.41)))
  </code></pre>
  
  <p>I would like to plot this as a bar plot with Position values 1-3, 4-6, 7-9, 10 in separate plots, i.e. 4 separate plots below each other. Is there an easy way of doing this in ggplot?</p>
  
  <p>EDIT: I would like to achieve this without having empty Positions.</p>
  
  <p>Cheers,
  Joseph</p>
