Great book; however, data for examples 2.18-2.21 would be very helpful

Thanks, Mark. As soon as the semester ends, I'll fix this problem.

I couldn't add a comment to the score-factor-ordered.R script so I will add it here. I think that

ordered(score)

is more common and self-explanatory than

factor(score, ordered = TRUE)

Also, note that the ordering of A < B < C < D is not what we would usually think of for letter grades. It may be better to use

ordered(grades, levels = LETTERS[4:1])
