	Uh, you don't ack-chewally want that ``\n'' in there with
	a print() statement.  (You'd want it with a cat() statement.)

	Did you mean ``test.R'' here, rather than ``temp.R''?
	If not, what's in ``temp.R''?

	Well, it works for *me*!

	I made a file temp.R containing the line ``print("test of batch")
	and then did:

	R CMD BATCH temp.R temp.out

	The resulting file temp.out contained the ``test of batch'' line
	as expected/required.

	No problema.

	Clearly the R gods don't like you. :-)
