title: Choosing between qplot() and ggplot() in ggplot2
body: <p>I'm starting to use the great <code>ggplot2</code> package for plotting in R, and one of the first things I ask myself before each plot is <em>"well, will I use <code>qplot</code> or <code>ggplot</code> ?"</em></p>
  
  <p>I understand that <code>qplot</code> provides a simpler syntax while <code>ggplot</code> allows maximum features and flexibility, but what is the function you use the most, and do you have some precise use cases for each one ? Do you use mostly <code>qplot</code> and <code>ggplot</code> only for complex plots, or do you use <code>ggplot</code> everytime ?</p>
  
  <p>Thanks for your feedback !</p>
