yes you can, r will let you:
assign(FALSE, TRUE)
ls()
# see FALSE
get(FALSE)
# see TRUE
this does not matter much, as r

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

To save my fingers and still being on the safe side, I always do:
!0
[1] TRUE
!1
[1] FALSE
;) ...still hackable though.

How about
!!0 # FALSE
!!1 # TRUE
Although its one more char, its very easy to press ! twice and when you
look at it its more obvious since 0 is associated with FALSE and
1 with TRUE.

Fair enough. But I find my interactive data analysis jobs quickly get
big enough (data manipulation, a series of model fits, some customised
output) for the analysis script to turn into something that looks like a
program. Of course, YMMV. I also get annoyed at code that uses = for
assignment
Sampling with and without replacement
I seem unable to use replace = F when I want to sample without
replacement. I would think
that it comes down to F is not a legitimate abbreviation for FALSE.
except that
Dalgaard (p. 118) uses F for FALSE and it works

It is better programming practice to use FALSE for false and TRUE for
true, and not F and T. This is because it is quite legal to do this:
T - FALSE
F - TRUE
or any other assignment. If you re-assign T or F (which are set to TRUE
and FALSE at the beginning of a session), you run into the sort of
10 matches
