title: Adding a footnote / thanks to Rmarkdown title slide
body: <p>I have to include a note in my title slide declaring the source of my funding. I was able to do this in LyX / LaTeX through:</p>
  
  <pre><code>\author{Michael Chirico\thanks{These people gave me money}, Other Authors}
  </code></pre>
  
  <p>I have not been able to reproduce this in Rmarkdown. The <a href="http://rmarkdown.rstudio.com/authoring_pandoc_markdown.html#footnotes">site</a> mentions using <code>[^]</code> anchoring to mark footnotes, and this works fine in other slides, but I couldn't get it to work in the title:</p>
  
  <pre><code>---
  title: "Title"
  author: "Michael Chirico[^thanks], Other Authors"
  date: "February 10, 2016"
  output: beamer_presentation
  
  [^thanks]: These people gave me money
  ---
  </code></pre>
  
  <p>The .pdf compiles but there is no title slide. I think this is the relevant part of the compilation log:</p>
  
  <blockquote>
    <p>pandoc: Could not parse YAML header: UnexpectedEvent {_received = Just (EventSequenceStart Nothing), _expected = Nothing} "source" (line 1, column 1)</p>
  </blockquote>
  
  <p>If I move <code>[^thanks]</code> outside the header, the .pdf compiles but there is no footer on the title page (nor anywhere else), and <code>[^thanks]</code> appears as-is on the title slide.</p>
  
  <p>How can I add a footnote/thanks section to the title slide?</p>
