Exercise

Scatterplots

This exercise will continue to expand the ggplot2 layers with geom_point() for creating scatterplots and geom_smooth() to add a local regression (loess) fit line. You'll also add another layer facet_wrap(vars(x)) to obtain a panel plot by a third variable x.

The ggplot2 and dplyr packages and the abalone dataset are already loaded for you.
