Here is the link to a ggplot2 demo I presented at the InveRness RUG last week :

intro to ggplot2

It’s in ioslides (html) format, for best viewing press F on your keyboard for full screen, and toggle widescreen on/off with the W key.

It’s for beginners / those new to ggplot2.

This is just scratching the surface of this amazing package.

Hope this helps get you started..
