As I see it R is saying 'I am doing what you told
me, but just in case I am checking whether that
was what you really wanted'. Note that you do not
get a warning if there was only one place R could
put it. I would certainly vote for a message if
people are getting unnecessarily alarmed by the warning.
Bump.

warning(gettextf("argument 'lib' is missing: using '%s'", lib),
immediate. = TRUE, domain = NA)
}
If I were patching this I would simply comment out this whole test
(rather than making a message() Ã la Jari Oksanen) -- it seems to
make the most sense to execute the documented behavior silently ...
I will submit this as a wishlist item shortly if no-one complains.
