Week 5 notes updated

[eeholmes]

I have updated the week 5 notes and added comments based on the Q & A discussion. Video on Tuesday.

Note, I corrected my info about how data "flows" or is inherited from ggplot() in your ggplot code and give a bunch more examples. What I said in the Q&A (and lecture briefly) was not quite correct.
