title: Dplyr not installing
body: <p>Took a quick google search and couldn't find any issues like this.</p>
  
  <p>I'm trying to install <code>dplyr</code> but it freezes part way through.</p>
  
  <pre><code> install.packages("dplyr")
   Installing package into ‘W:/Documents/R/win-library/3.3’
   (as ‘lib’ is unspecified)
   also installing the dependencies ‘assertthat’, ‘R6’, ‘Rcpp’, ‘magrittr’,

  </code></pre>
  
  <p>After that it just stops and doesn't move on to <code>BH</code> or <code>dplyr</code>.  It's been about 10 minutes and still says its running but nothing happening.  I deleted them out of the library and tried installing again, as well as another time from a different source.  No luck.  Any idea what's happening?</p>
