title: How to use --citeproc instead of pandoc-citeproc in RStudio when bibliography is used in an RMarkdown document?
body: <p>I get the following error when trying to render a RMarkdown document in RStudio  with bibliography specified in the YAML as <code>bibliography: references.bib</code>:</p>
  <pre><code>[WARNING] Deprecated: pandoc-citeproc filter. Use --citeproc instead.
  Error running filter pandoc-citeproc:
  Could not find executable pandoc-citeproc
  Error: pandoc document conversion failed with error 83
  
  &gt; rmarkdown::pandoc_version()
  [1] ‘2.11.0.4’

  <p>I cannot find the way to use <code>--citeproc</code> instead of <code>pandoc-citeproc</code>. Would appreciate any help. Thanks!</p>
