title: How to create a map chart with direction arrows in R?
body: <p>I'm looking at creating a few maps like this on the <a href="http://www.eia.gov/todayinenergy/detail.cfm?id=20592#tabs_Slider-5" rel="nofollow noreferrer">eia website site</a>. </p>
  
  <p>Would you be able to point me to direction in creating a map like this? Or is R not able to create such a chart? </p>
