title: Move r packages to new computer which has no internet
body: <p>Normally I install packages using:</p>
  
  <pre><code>install.packages("foo") 
  </code></pre>
  
  <p>and a Repo over the internet. But I have a new machine now where I want to replicate the packages from my existing installation without having to pull everything off the internet all over again. (I've a ton of packages and slow  internet access)</p>
  
  <p>Both machines are Windows and run the same R version. (2.13.1)</p>
  
  <p>Is there a way to do this? Closest I can get is I know I can install from local zip files using:</p>
  
  <pre><code>install.packages("pathtozip", repos = NULL)
  </code></pre>
  
  <p>But does R store all Zips somewhere? I found a few in locations like:</p>
  
  <pre><code>C:\Documents and Settings\foouser\Local Settings\Temp\RtmpjNKkyp\downloaded_packages
  </code></pre>
  
  <p>But not all. </p>
  
  <p>Any tips? </p>
