Well, as it states on the Help page, which should always be the first
place to look for, ummm, help:
"If the value of EXPR is not a character string it is coerced to
integer. Note that this also happens for factors, with a warning, as
typically the character level is meant. If the integer is between 1
and nargs()-1 then the corresponding element of ... is evaluated and
the result returned: thus if the first argument is 3 then the fourth
argument is evaluated and returned."
So following up on Bill's comment, the arguments do not even need to
be names when Stst evaluates to) an integer:
> Stst <- 2
> switch(Stst, print("NO"), print("YES"))
[1] "YES"
Cheers,
Bert
