I notice that NANs work correctly if they are part of the
dependent data, and are set to zero if part of the
independent data. While I guess you could make a case
to RSI that this is a bug, I find it really sort of
makes a little bit of sense to me, in the kind of
way that I find hard to explain. I mean, really,
shouldn't you *know* what the independent data is?
Shouldn't it *always* be defined? How else would
you plot anything? On the other hand, I find nothing
strange about the dependent data having numbers that
are occasionally unknown. It wouldn't be a real
experiment otherwise.

Sorry, but I'm approaching senility. :-(

Cheers,

David
