title: Installing gdata in R
body: <p>I tried to install package <code>gdata</code> with the following command, but got the message that follows:</p>
  
  <pre><code>install.packages(pkgs="gdata")  
  Warning in install.packages(pkgs = "gdata") :
  'lib = "C:/Program Files/R/R-3.1.3/library"' is not writable
  Error in install.packages(pkgs = "gdata") : unable to install packages
  </code></pre>
  
  <p>Seems the directory "library" should be writable, so what did I do wrong?</p>
