title: File.choose for multiple files R
body: <p>I have a short script that takes a list of csv files and does stuff to them. 
  The problem I am having is that the file names have to be written into the beginning of the file(filenames=c("file1","file2",...)).</p>
  
  <p>I did find <a href="http://stat.ethz.ch/R-manual/R-devel/library/base/html/file.choose.html" rel="nofollow">file.choose</a> to get the user to choose a file, but I need a list of files. </p>
  
  <p>Is there a way for the user to choose multiple files? </p>
