Just to add to the confusion, on my system I get NA --- which I

calls,
I get "bla" from each.
So, no bug in my system.
I've just built a 3.0.1 version, and I definitely see the bug there.
What do you get from these expressions?
str(min(NA, "bla"))
str(min("bla", NA))
str(min(NA_character_, "bla"))
I get
> str(min(NA, "bla"))
int NA
> str(min("bla", NA))
chr "bla"

chr "bla"
on both Windows and OSX R 3.0.1. After today's patch, I get
chr NA
for all three.
I get:
> str(min(NA, "bla"))
int NA
> str(min("bla", NA))
chr NA
> str(min(NA_character_, "bla"))
chr NA
Which looks to me to be as it should be. How come my system's so good
compared to others? :-)
cheers,
Rolf
