[R-marketing-bugs] Errata: Chapter 3, page 54 (Brackets left out)

[Chris Chapman]

Thank you for the note.

I cannot find this error. It appears to be correct in both the printed book
and the online code file -- see attached screenshot from the PDF for the
book, as well as the code here
<http://r-marketing.r-forge.r-project.org/code/chapter3-ChapmanFeit.R>.
Could you clarify where you found this mistake?

I hope you're enjoying the book! Cheers and best wishes,

-- Chris
