It is better programming practice to use FALSE for false and TRUE for

T <- FALSE
F <- TRUE
It may be better programming practice, but is it better interactive
data analysis practice? R isn't just a programming language, and
there are lots of good reasons to provide shortcuts that reduce
typing. It's very easy to forget that most people can't touch type at
a decent speed, and every key press less helps them get their ideas
from their head to the computer faster.
That would be an argument for T and F being the reserved words (as I
think they are in S-PLUS). But since it's so easy to use T or F as a
variable, the problems caused by using them as TRUE or FALSE are not
negligible -- look at the original question in this thread, which was
likely caused by using F as a variable.
