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.
