I was wrong here.  As Grame has pointed out (privately), the "?"
can well be used to indicate that it's not clear  *where* the
bug is. 

    MM> (and your definitely is).

because  help(summary)  really tells you about the `digits ='
argument which is applied with some inconsistency in the
different summary() methods.
The reason for this has been S(-plus) compatibility that we
didn't want to drop too quickly.

or proposals about changing R behavior on R-devel.
I think there's a point here that could be discussed: Changing
current behavior while trying to remain S compatible as much as
possible.

    MM>   And this has become  almost a FAQ.
an exaggeration.
But people have been told quite a few times to use something
like  summary(*, digits = 7) if they wanted different behavior.

and hereby apologize to Graeme.
