title: Define Excel's column width with R
body: <p>The final product is an Excel CSV spreadsheet which has more than 250 columns.
  I was wondering if there was a way to determine the column width in Excel from R?</p>
  
  <p>I am using write.csv2, which produces column width in excel all equal to 8,43. </p>
  
  <blockquote>
    <p>write.csv2(df, na = "", file= "Final.csv")</p>
  </blockquote>
  
  <p>If possible I am looking for a trick to vary all of them at once or only specific ones.
  Is <a href="https://stackoverflow.com/questions/19404270/run-vba-script-from-r">running VBA from R</a> my only option? </p>
  
  <p>Thank you for your help!</p>
