title: R plot - how to add notes and description to the plot?
body: <p>I have a long description for my plot. And I also need to put some other information under the plot as well.</p>
  
  <p>But I can't figure it out how I can do it. This is what I have so far,</p>
  
  <pre><code>plot(1:10)
  title(
     main = "Foo", 
     sub = 'Description \n Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. Aenean massa. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. ', 
     font.sub = 1, 
     font.main = 1
  )
  </code></pre>
  
  <p>result is not good as the description is too long and it has been cut off, also the word description is overlapping with the xlable,</p>

  <p>How can I box the description under the plot?</p>
  
  <p>This is what I am after,</p>

  <ul>
  <li>an additional info - time period.</li>
  <li>wrap the description in a grey box.</li>
  <li>adjust the text to the left.</li>
  </ul>
  
  <p>Are these possible?</p>
