title: How do I get ggplot to order facets correctly?
body: <p>I am trying to facet about 14 plots based on a variable that runs from 2-14. The plots show up in the order: 
  10,11,12,13,14,15,2,3,4,5,6,7,8,9</p>
  
  <p>How do I get them to order from 2-15?</p>
  
  <p>update: ok, so I made it a factor using <code>data$var=as.factor(data$var)</code>. 
  The Levels are 
  <code>Levels: 10 11 12 13 14 15 2 3 4 5 6 7 8 9</code></p>
  
  <p>How do I reorder those?</p>
