No worries. I've hacked your code far enough to be usable for this to
me, but it is far from robust or elegant. I guess our solutions are
similar, and assume well behaved users. We all know that those are few
and far between.
Enjoy the tennis,

Currently, yes. But who knows. I can see this being
useful in my own work. In fact, I've already solved this
problem in my own work (using Histplot as the example),
but just not in a way that would be useful to
everyone.
It's a busy week, what with work, a big tennis tournament
that has me playing nearly every evening, my wife gone to
take care of her brother, etc. But, I'll see if I can come
up with something. :-)
Cheers,
David

I have another one for you: how can I use histoplot to plot a
histogram?
Confused? Let me explain: If I use the histogram function to create a
histogram of data from many files (say a seasonal average of a
quantity measured from a satellite), and then would like to use
histoplot to show the result, then I'm currently out of luck, right?
Best,
Maarten
