Hello anyone used 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! -------------- Best wishes, John Shanghai Institutes of Biological Sciences, Chinese Academy of Sciences, 320 Yue Yang Road, Shanghai 200031 Tel?86-21-54921107 Fax?86-21-54921101 ----------------------------------------------------------------------- The information transmitted in this electronic communication is intended only for the person or entity to whom it is addressed and may contain confidential and/or privileged material.

the C function drawing a rectangle: heatmap() -> image() -> do_image() -> GRect() -> GERect() -> rect() -> do_rect() -> GRect() ??

I see GRect() calling GERect() calling dd->dev->rect(), i.e. a function in the current device structure. This will typically have been set to something like X11_Rect() or Cairo_Rect() or ....

But rect() still seems to call -> do_rect() -> GRect(), and thus turns back?? How do you consider this strange thing?

GRect/GERect do NOT call rect()!!!!! Please read what I wrote....
