title: Creating a new folder with extension and current date
body: <p>I was wondering if someone has an idea if it is possible to create a new folder within R and write the current date automatically to it, e.g. New Folder: "TEST_20140903"? Is this possible?</p>
  
  <p>What I am attempting to do is to move my output (several thousands plots) into a new folder and then each time I am running the script the current date should be written in the extension.</p>
