+    A ggplot2 extension package to teach/learn the logic of the prop test.
+  description: >
+   ggprop.test has functionality to allow you to walk through the logic of the prop test step-by-step: 1. Draw bar chart (stacks) for each category (false and true case). 
+   2. Draw theoretical limits for proportion (0 to 1). 3. Calculate proportion and place it in the logical limits (i.e. the balancing point for stacks).  
+   4. Place null within the logical limits  5. Draw distribution for NULL and standard deviations within the distribution.  6. determine the z-score (where does observed prop fit into NULL distributions) 
+   (i.e. how many standard deviations fit between .5 and .67)
