R devel - Dec 1998 - Saving and replaying plots

Is a mechanism for saving and replaying later the content of the current
graphic device hidden somewhere? Or is it planned?

If not, I would like to have something of this sort so I can try to
implement it (when I will have some time,of course) and if:
1) it is simple as graphics.c/copyDisplayList(...) suggests, i.e,
   it is enough to duplicate, save and restore (device)->dpSaved and 
   (device)->DisplayList;
2) idea is sensible; in particular, I have no idea of how much
   memory is `eaten' by the DisplayList of a `medium size' plot.

I don't think the feature is available now, but it should be pretty
easy to implement.  The display list consists of a list of function
calls to the low level functions.  These can be quite large.

There are some potential difficulties in loading a previously
saved display list.  I'll have a bit of a look.
