title: put a HTML link to the R Shiny application
body: <p>I want to put a HTML link (actually it redirects to <strong>file://...</strong>) on the R Shiny user interface, so that end-users can just click it and go to that page in another tab in Chrome. Is there a way to do that? Where shall I put? In the ui.R file or in the server.R file? </p>
  
  <p>I find a post here: <a href="http://www.r-bloggers.com/more-explorations-of-shiny/">http://www.r-bloggers.com/more-explorations-of-shiny/</a> but I am not sure how to use the <code>a()</code> function...</p>
  
  <p>Note: I know how to do that (see my comments below), but since I am redirecting to a <code>file://</code> destination, the link won't work. Any solutions?</p>
  
  <p>Thanks!</p>
