title: NVD3 Bullet Chart with rCharts
body: <p>Wondering if it is possible to produce an NVD3 Bullet Chart (<a href="http://nvd3.org/examples/bullet.html" rel="nofollow">http://nvd3.org/examples/bullet.html</a>) directly via rCharts ?</p>
  
  <p>Poking around it seems like Nvd3.R might lack the ability to properly pass the required (ranges, measures, and markers) arguments down into D3 - but I'm not sure.</p>
  
  <p>Thanks !</p>
