title: R Keeps Downloading Packages to tmp Directory
body: <p>I am using R Studio on a 2103 MacBook Pro.  I had no problems before downloading and installing packages, but recently all my packages are being downloaded and then fail to install:</p>
  
  <pre><code>trying URL 'http://cran.rstudio.com/bin/macosx/mavericks/contrib/3.1/manipulate_1.0.1.tgz' 
  Content type 'application/x-gzip' length 33770 bytes (32 Kb) 
  opened URL
  ==================================================
  downloaded 32 Kb
  
  The downloaded binary packages are in
  /var/folders/yl/7q0_4h3j60d5pp52vmz0b06r0000gn/T//Rtmpa4oYSr/downloaded_packages
  </code></pre>
  
  <p>.libPath() returns the correct location of my R libraries (not this)</p>
  
  <p>I can install manually from the downloaded package, but this extra step is Very Annoying, and I would like to restore the correct behavior.  </p>
  
  <p>Someone seems to have had the same problem <a href="https://stackoverflow.com/questions/21837036/install-packages-r-on-ubuntu-12-04-downloads-but-does-not-install-packages">here</a>.  The solution was to add more swap space.  This does not seem to be my issue as ample swap and RAM appear to be available on my machine.</p>
  
  <p>Has anyone had and resolved this issue?</p>
