That means the return value of me.probit() has been marked as invisible, so it won't auto-print.  You have to use an explicit print

	print(me.probit(obj))

or use your work-around to convince R that you actually meant to print the output.

If you dig through the full code of me.probit(), you'll probably find the function invisible() called somewhere.

Best,
