title: How can I ask a user and read those files(s) into separate dataframes?
body: <p>I have various data files in a folder. I want to create a format where I ask the user for a particular filename or names (Or I mention it in a particular list in the code) and the code reads those particular file(s) into separate dataframes. How can I do it?</p>
  
  <pre><code>01608500.dat
  01608100.dat
  01608520.dat
  41608500.dat
  </code></pre>
  
  <p>I have been able to list the files using this:</p>
  
  <pre><code>files&lt;-list.files(path="data",pattern="*.dat", full.names=TRUE)
  </code></pre>
