On the bottom of p. 238, in table 9.4 "Special symbols used in R formulas" of section 9.2 "Fitting ANOVA models", is the expand carrot example correct?

The short example is "y ~ (A+B+C)^2", the expanded version is "y ~ A + B + C + A:B + A:C + A:B" (emphasis added). In the expanded version, is the second "A:B" correct?

Re: p. 238 typo
It should be y ~ A + B + C + A:B + A:C + B:C

I have made the correction.
