yes, fix the function definitions :-)

Of course your `tight time constraints' are now over anyway...

The reason I'm writing:
In the last few days I've also extensively made use of
the `cluster' package, and found myself that the plotting functions are not
really flexible enough sometimes.

I've fixed many of them and also improved on the help files of cluster
(some of which come out with text in the wrong order).

I plan to shortly submit my patches to Kurt Hornik, the official maintainer
of "cluster".

Before that, I'd be quite interested in wishes,
feedback from you and other users, if you have!

you're welcome.
