title: Combining data frames with missing data frames with rbind
body: <p>I am using the following command for combining data from different dataframes.Some of the data frames are missing like data 4 etc.,</p>
  
  <pre><code>filings&lt;- rbind.pages(list(data1,data2,data3,data4,data5))
  Error in stopifnot(is.list(pages)) : object 'data4' not found
  </code></pre>
  
  <p>I am getting the above error. I have about 1000 data frames and there are some missing dataframes which are not known. Is there way I can tackle this issue to skip missing data frames?</p>
  
  <p>Thanks!</p>
