title: Rstudio knit to PDF
body: <p>The new version of Rstudio (0.98.932) has many new options including knit to PDF. An article describing the new version has a <a href="http://blog.rstudio.org/2014/06/18/r-markdown-v2/#comment-10850">comment from Dave</a> that says:</p>
  
  <blockquote>
    <p>...after installing rstudio 0.98.932 I don’t get the little dropdown menu
    for knit-pdf or word when editing a .Rmd file.</p>
  </blockquote>
  
  <p>I'm having the same issue. A helpful response was posted:</p>
  
  <blockquote>
    <p>It might be that either:</p>
    
    <p>a) You are not running R 3.0 (which is required for RMarkdown v2); or</p>
    
    <p>b) You have a custom markdown renderer defined (markdownToHTML
    option). You can check for this by executing:</p>
    
    <p>getOption(“rstudio.markdownToHTML”)</p>
  </blockquote>
  
  <p>That solved Dave's problem (b), but when I run that command I get NULL</p>
  
  <pre><code>&gt; getOption("rstudio.markdownToHTML")
  NULL
  </code></pre>
  
  <p>Which I assume means I don't have a custom markdown renderer defined. (Previously I did in a cusomized <code>.Rprofile</code>, but I removed that.) My R version is 3.1.0.</p>
  
  <p>Am I misunderstanding the <code>getOption</code> command? Could something else be tripping up my Rstudio?</p>
