title: Unused arguments while using read.xlsx
body: <p>I am new to R, please help :)
  I am trying to read a file using <code>read.xlsx()</code> (from the package <code>xlsx</code>) in R. I am getting the following error: </p>
  
  <pre><code>Error in read.xlsx("survey_all", stringsAsFactors = F) : 
    unused argument (stringsAsFactors = F)
  </code></pre>
  
  <p>Why does it say unused argument? </p>
