title: Install package in R
body: <p>I am trying to install rscproxy and rcom packages on windows. I tried the following methods:</p>
  
  <p><strong>Method 1:</strong></p>
  
  <p>Opening R as administrator and using this command</p>
  
  <pre><code>&gt;install.packages(c("rscproxy","rcom"),repos="http://rcom.univie.ac.at/download",lib=.Library)
  </code></pre>
  
  <p>But getting error as unable to access the url.</p>
  
  <p><strong>Method 2:</strong></p>
  
  <p>Downloaded the zip of the packages from cran and using this command</p>
  
  <pre><code>&gt;install.packages('D:\\rscproxy_2.0-5.zip', lib='C:\\Program Files\\R\\R-3.1.1\\library',repos = NULL)
  package ‘rscproxy’ successfully unpacked and MD5 sums checked
  &gt; install.packages('D:\\rcom_2.2-5.zip', lib='C:\\Program Files\\R\\R-3.1.1\\library',repos = NULL)
  package ‘rcom’ successfully unpacked and MD5 sums checked
  </code></pre>
  
  <p>But then:</p>
  
  <pre><code>&gt; library(rcom)
  Error: package ‘rcom’ was built before R 3.0.0: please re-install it
  </code></pre>
  
  <p>I also referred these <a href="https://stackoverflow.com/questions/1474081/how-do-i-install-an-r-package-from-source">How do I install an R package from source?</a> and <a href="https://stackoverflow.com/questions/14806705/manually-downloading-and-installing-packages-in-r">Manually Downloading and Installing Packages in R</a> but all in vain.</p>
  
  <p>Please help me with any fix for this.</p>
  
  <p><strong>P.S : I am using R 3.1.1 on 32-bit Windows 7</strong></p>
