Purpose

This was to familiarize myself with writing functions to speed up things I have to do often!

Summary

Given two data sets (dfA and dfB), I wrote a function to do the following:

• Merge them
• Print the number of rows from the returned dataset in dfA AND dfB
• Print the number of rows from the returned dataset in dfA BUT NOT dfB
• Print the number of rows from the returned dataset in dfB BUT NOT dfA
• Print some diagnostic statistics
