title: money representation in R
body: <p>I would like to know how can I work with money with R. It means, do arithmetic, print well formatted numbers and etc.</p>
  
  <p>For example I have some values</p>
  
  <pre><code>1.222.333,37 
  1.223.444,88
  </code></pre>
  
  <p>I could translate it to numeric and round it, removing the cents, but there isn't a better pattern to work with? I did try the format method, something like:</p>
  
  <pre><code>format(141103177058,digits=3,small.interval=3,decimal.mark='.',small.mark=',')
  </code></pre>
  
  <p>but without success. any tip or ideas?</p>
