the C function drawing a rectangle: heatmap() -> image() -> do_image() -> GRect() -> GERect() -> rect() -> do_rect() -> GRect() ??
...to do similar things: search for the final C function that corresponding to the drawing of a rectangle?
As listed in the subject, I started from heatmap() in R and after several steps reached the GRect() in C. However, then it refers to rect() which further seems to refer to do_rect(), and then, surpringly, do_rect refers to GRect()!!! A dependency circle! How can it work if no functions soly taking the job for drawing a rectangle?
I know there must be somewhere wrong in my above function "chain", and can you help me to find it out? Many thanks!

Polynomiographic function in R :-)
...are likely better ways than those I used. For example, even if
unlikely, there might be clashes between the variables making up the
expression given, and local variables of the function. I wonder if the
expression variable could have been more fully "abstracted".
* Vectorisation worked surpringly well on that problem, speed-wise.
However, because some regions of the plane converge faster than others
(use `display=plot' and such while calling `polygraph' to study this),
maybe they would be ways towards significant speed-ups. But since it is
likely that one would loose a good part of...
