title: What function to use as argument when decompressing GZ files using LDPLY( )
body: <p>I have a folder of over 500 GZ format files that need to be decompressed but I cannot find the argument needed for .fun argument. This code works for all other formats, except GZ.</p>
  <pre><code>GZ_files &lt;- list.files(path = data_dir_test, pattern = &quot;*.gz&quot;,
                     full.names = TRUE, recursive = TRUE)
  
  ldply(.data = GZ_files, .fun = ??? , exdir = data_dir_test)
  </code></pre>
  <p>What argument can I use for .fun to decompress my gz files? The files are not tared.</p>
  <p>Thanks a lot!</p>
