title: render function not recognised in R Studio
body: <p>Bit of a newbie for <code>R</code>, <code>R Studio</code> and <code>Markdown</code> but I am trying to use the <code>render()</code> function on my <code>Rmd</code> file and I get the following error:</p>
  
  <pre><code>Error: could not find function "render"
  </code></pre>
  
  <p>If I try to use the following I get this error:</p>
  
  <pre><code>markdown::render("MarkdownExample.Rmd")
  Error: 'render' is not an exported object from 'namespace:markdown'
  </code></pre>
  
  <p>Still yesterday I could use the render fonction without any problem. Would anyone know what to do?</p>
  
  <p>Thanks in advance</p>
