title: Use R to create chart in Excel sheet
body: <p>I am using <code>openXLSX</code> package to generate excel files from my <code>R</code> output.<br>
  There is no way I have found to add excel charts to the excel workbook.<br>
  I saw that <code>python</code> has a  module for <a href="http://xlsxwriter.readthedocs.io/chart.html" rel="noreferrer">creating Excel files</a> that has a class for adding excel charts.<br>
  Is there a way to do this with R?</p>
