title: combine files using join_all
body: <p>I am trying to join files using the following command:</p>
  
  <pre><code>join_all(dfs = datalist,by = "V1",type="left",match="all") 
  </code></pre>
  
  <p>The problem is that when I use <code>type="full"</code> it does not combine the files, but if I use <code>type="left"</code> it works. However, I need the fll data set.</p>
  
  <p>Any ideas why or suggestions on another method?</p>
