title: Use of LaTeX Syntax in R Presentation (`.Rpres`) Slide Title
body: <p>I had a question about the us of LaTeX syntax in a Slide Title in R Presentation. The use of LaTeX as you would for a R markdown file works fine for the text in the actual body of the slide, but not the title. Example:</p>
  
  <pre><code>    $PM_{2.5}$ Concentrations
      =================================
  
      Graph of $PM_{2.5}$ concentrations
  </code></pre>
  
  <p>In this example, when the presentation file is run, the title will show exactly as is, whereas the information in the body of the slide will show as you would expect it to be shown as a LaTeX equation.</p>
  
  <p>I have tried other general markdown functions in this title portion of each slide with similar results (i.e. <code>~~strikethrough~~</code>).  </p>
