Formula notation

As well as the vars() notation for specifying which variables should be used to split the dataset into facets, there is also a traditional formula notation. The three cases are shown in the table.

| Modern notation                            | Formula notation  |
|--------------------------------------------|-------------------|
| facet_grid(rows = vars(A))                 | facet_grid(A ~ .) |
| facet_grid(cols = vars(B))                 | facet_grid(. ~ B) |
| facet_grid(rows = vars(A), cols = vars(B)) | facet_grid(A ~ B) |

mpg_by_wt is available again. Rework the previous plots, this time using formula notation.
