title: Turning off title page in Rmd using knitr
body: <p>Edit:</p>
  
  <p>Desired result can almost be reached, when overriding pagestyle "plain" and using documentclass article.</p>
  
  <pre><code>\fancypagestyle{plain}{
     \fancyhf{}
     \fancyhead[RO,RE]{Header}
     \fancyfoot[RO,RE]{\thepage}
  }
  </code></pre>
  
  <p>The problem I am facing no is that the headsep (space between header and table) is greater on the first page. This seems to be because of \maketitle. When removing </p>
  
  <pre><code>$if(title)$
  \maketitle
  $endif$
  </code></pre>
  
  <p>from the (default) pandoc template everything works as expected. 
  Imho the same result should also be reachable (without editing the template) but using "title: false" in the yaml-header in my .rmd file. But the "\maketitle" command seems to be there anyways when looking at the generated .tex. Why is that?</p>
  
  <p>Original Question:</p>
  
  <p>I'm trying to turn off the titlepage when creating a pdf using knitr. The document contains a longtable with repeated headers.</p>
  
  <p>I'm expecting a pdf, where all pages have header and footer Information (and headsep) as specified. In the running example below page 1 behaves differently. Attempt to disable titlepage was not successfull.</p>
  
  <p>test.Rmd</p>
