title: R: Add values to waterfall chart
body: <p>I am using the <a href="http://cran.r-project.org/web/packages/waterfall/index.html" rel="nofollow noreferrer">waterfall package</a> in R to prepare waterfall charts and like to add the values to the chart.</p>
  
  <p>Example code (taken from <a href="http://lamages.blogspot.de/2012/05/waterfall-charts-in-style-of-economist.html" rel="nofollow noreferrer">http://lamages.blogspot.de/2012/05/waterfall-charts-in-style-of-economist.html</a>):</p>
  
  <pre><code>library(latticeExtra)
  library(waterfall)
  data(rasiel) # Example data of the waterfall package
  rasiel
  #    label          value   subtotal
  # 1  Net Sales       150    EBIT
  # 2  Expenses       -170    EBIT 
  # 3  Interest         18    Net Income
  # 4  Gains            10    Net Income
  # 5  Taxes            -2    Net Income
