Margin plots

Facets are great for seeing subsets in a variable, but sometimes you want to see both those subsets and all values in a variable.

Here, the margins argument to facet_grid() is your friend.

  • FALSE (default): no margins.
  • TRUE: add margins to every variable being faceted by.
  • c("variable1", "variable2"): only add margins to the variables listed.

To make it easier to follow the facets, we've created two factor variables with proper labels — fam for the transmission type, and fvs for the engine type, respectively.

Zoom the graphics window to better view your plots.
