Getting ready
Make sure that the auto-mpg.csv file is in the working directory of R. Read the file using the read.csv command and save in the auto variable. Convert cylinders to a factor variable. If you have not done so already, install the ggplot2 package as follows:
> install.packages("ggplot2")> library(ggplot2)> auto <- read.csv("auto-mpg.csv", stringsAsFactors=FALSE)> auto$cylinders <- factor(auto$cylinders,labels=c("3cyl","4cyl", "5cyl","6cyl","8cyl"))
