title: How to Convert Numeric Data into Currency in R?
body: <p>Searched Google and SO and couldn't find a good answer. I have the following table:</p>
  
  <pre><code>      Country     Value
  23    Bolivia  2575.684
  71     Guyana  3584.693
  125  Paraguay  3878.150
  49    Ecuador  5647.638
  126      Peru  6825.461
  38   Colombia  7752.168
  151  Suriname  9376.495
  25     Brazil 11346.796
  7   Argentina 11610.220
  171 Venezuela 12766.725
  168   Uruguay 14702.505
  37      Chile 15363.098
  </code></pre>
  
  <p>All values are in US dollars - I'd like to add in the dollar signs and the commas. Bolivia's value should therefore read $2,575.684. Also, is there any real need to change row names to 1 through 12? If so, an easy way to do so?</p>
  
  <p>Thanks in advance.</p>
