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,
