Sorry, I wasn't clear.  I meant to ask what error message you get if you 
run the command that's supposed to generate a warning, i.e. run the code

ap1 <- available.packages(repos = "http://foo.bar")
ap2 <- available.packages(repos = "http://foo.bar")

and you'll likely see a warning on the first line, and an error on the 
second.  The text of that error may be informative.
