title: New names: * `` -> `..18` message in R console
body: <p>I ran a Rshiny app and it works as expected but in console I get the following message:</p>
  
  <pre><code>New names:
  * `` -&gt; `..18`
  </code></pre>
  
  <p>what does it mean?</p>
  
  <p>It occurs when I try to do this</p>
  
  <pre><code>&gt; data1&lt;-read_excel("CUMMULATIVE COLLECTION POS_UPLOAD.xls")
  New names:
  * `` -&gt; `..18`
  </code></pre>
  
  <p>When I do the same operation again it doesn't gives the message</p>
  
  <pre><code>&gt; data2&lt;-read_excel("DATA.xlsx")
  </code></pre>
