Exercise 3.2.5 requires a minor change to be correct

[mubangansofu]

Based on the Exercise question, the ordinate should be class, hence our code should swap the positions of x and y. One can write

mpg %>%
ggplot()+
geom_point(aes(drv,class))

or

ggplot(mpg, aes(x = drv, y = class)) +
geom_point()

@mubangansofu Thank you so much for pointing this out. :)
Initially, I got confused since in exercise 3.2.5 it says "[..] class vs drv [...]".
Thus, the variable "drv" should be plotted on the horizontal bar and the variable "class" on the vertical bar.
