\description{
Generally, you do not need to print or plot a ggplot2 plot explicitly: the
default top-level print method will do it for you. You will, however, need
to call \code{print()} explicitly if you want to draw a plot inside a
function or for loop.

colours <- c("class", "drv", "fl")

print(ggplot(mpg, aes(displ, hwy, colour = .data[[colour]])) +
