How do you draw a boxplot without specifying x axis?

Question

The base graphics can nicely plot a boxplot using a simple command

data(mtcars)
boxplot(mtcars$mpg)

Answer 1

You can also use latticeExtra, to mix boxplot syntax and ggplot2-like theme:

bwplot(~mpg,data =mtcars,
        par.settings = ggplot2like(),axis=axis.grid)
