title: RAPPORT does not export table in R Markdown
body: <p>Thank you for the interesting package RAPPORT. I want to create a rapport table in a R Markdown document using RStudio but it passes the knitr commands instead of creating html code for table. It works when I run commands one by one in R command line. </p>
  
  <p><strong>Here is the Markdown code chunk:</strong></p>
  
  <p><code>{r t,  cache=FALSE }
  rpt = rapport.html('Descriptives.tpl', data=chrt.patients, var="RACE",file.name="Race",file.path="c://hdds//work//california//R Analysis/tmp")
  </code></p>
  
  <p><strong>Here is its output when I compile R Markdown using knitrHtml button:</strong></p>
  
  <p><div class="snippet" data-lang="js" data-hide="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;p&gt; &amp;quot;## Description&amp;quot; attr(,&amp;quot;class&amp;quot;) [1] &amp;quot;knit_asis&amp;quot; attr(,&amp;quot;knit_cacheable&amp;quot;) [1] TRUE[1] &amp;quot;template will return descriptive statistics of a numerical or frequency table of a categorical variable.&amp;quot;</code></pre>
  </div>
  </div>
  </p>
  
  <p><strong>Here is the output when I execute code line by line and have the right results:</strong></p>
  
  <p><div class="snippet" data-lang="js" data-hide="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;h2 id="description"&gt;Description&lt;/h2&gt;
  &lt;p&gt;This template will return descri\ptive statistics of a numerical or frequency table of a categorical variable.&lt;/p&gt;
  &lt;h3 id="race"&gt;&lt;em&gt;RACE&lt;/em&gt;&lt;/h3&gt;</code></pre>
  </div>
