Clarify documentation in mpg: very minor

[MaraAlexeev]

I was working through exercises using mpg in ggplot2 Elegant Graphics for Data Analysis, and I got stuck on trying to figure out what a drive train was.

I finally realized the variable drv means drive train. Could the documentation be updated to identify drv as meaning drive train?

Currently:
drv f = front-wheel drive, r = rear wheel drive, 4 = 4wd

Suggested:
drv the type of drive train, where f = front-wheel drive, r = rear wheel drive, 4 = 4wd

Thanks, sounds good to me. Do you want to try to create a pull request? You need to modify R/data.R and regenerate the doc by devtools::document().

ggplot2/R/data.R

Line 103 in b842024

#' \item{drv}{f = front-wheel drive, r = rear wheel drive, 4 = 4wd}

I will! Thanks.
