I think it would be useful to move away from ggformula and instead present only ggplot2 as the way graphics are produced. Since ggplot2 is currently the defacto industry standard and presented late in the text anyway, we should forego using ggformula and just jump straight into ggplot2.
This is a significant change. There are some papers, mostly by Randy Prium, about the efficacy of using ggformula. We should read these and discuss before committing to this change.
