title: Label lines in a plot
body: <p>I am plotting two lines using</p>
  
  <pre><code>plot(x, y, type = "l", color = "red")
  </code></pre>
  
  <p>and </p>
  
  <pre><code>points(x2, y2, type = "l", color = "blue")
  </code></pre>
  
  <p>I want to be able to add a label next to each line (instead of a legend).
  I am pretty sure it is possible using the package in <a href="http://directlabels.r-forge.r-project.org/" rel="nofollow noreferrer">http://directlabels.r-forge.r-project.org/</a>.</p>
  
  <p>Yet, I don't find an easy way of doing that.</p>
