Yes.  Why can't people call install.packages() correctly?  It has two
required arguments.  If R_LIBS is set, you do want to think hard about
where to install, and the warning is useful.  Maybe if there is only one
library, the warning could be suppressed.

And if they are doing it on Windows, they can use a menu item to generate
a correct call for them....
