title: Install R Package XML in Debian / Ubuntu
body: <p>I am just getting started with Ubuntu and want to program in R.  I successfully installed the latest version of R (currently 2.12.2) from the terminal.  I then attempted to run the following command:</p>
  
  <pre><code>&gt; install.packages("XML")
  Installing package(s) into ‘/usr/local/lib/R/site-library’
  (as ‘lib’ is unspecified)
  Warning in install.packages("XML") :
    'lib = "/usr/local/lib/R/site-library"' is not writable
  Would you like to create a personal library
  '~/R/i686-pc-linux-gnu-library/2.12'
  to install packages into?  (y/n) 
  </code></pre>
  
  <p>Should I create the personal directory or did I miss a step somewhere that allows me to write to the site library.</p>
  
  <p>Thanks in advance.</p>
