title: Can't install PDQ tool for R on windows
body: <p>I've been trying for half an hour following this simple guide <a href="http://www.perfdynamics.com/Tools/PDQcode.html#tth_sEc1.1.1" rel="nofollow">http://www.perfdynamics.com/Tools/PDQcode.html#tth_sEc1.1.1</a></p>
  
  <p>It simply throws this error:</p>
  
  <pre><code>&gt; install.packages("C:\\Users\\Neven\\Downloads\\pdq_6.0-1.tar.gz",repos=NULL,type="source")
  
  Warning: invalid package 'C:/Users/Neven/Downloads/pdq_6.0-1.tar.gz'

  <p>I've been searching for an answer on the website, trying different things but nothing did it.</p>
