No way: Think
factor(dead, levels=c(1, 2), labels=c("TRUE", "FALSE"))
(People are not _that_ unlikely do that. E.g., the tradition in
epidemiology is to label tables with +/- in that order.)
Anyways, Brian points out (privately) that it used to work as documented
prior to v.2.6.0, so there's not likely to be that much of a problem
with reinstating that behaviour.
