title: How to left align text in annotate from ggplot2
body: <p>My example is:</p>
  
  <pre class="lang-r prettyprint-override"><code>qplot(mtcars$mpg) + 
    annotate(geom = "text", x = 30, y = 3, label = "Some text\nSome more text")
  </code></pre>
  
  <p>How do I get the text here to be left aligned? So that the 'Some's line up with each other.</p>
