[R] curiosity question: new graphics vs. old graphics subsystem

hi paul: thank you. great explanation.
* what you describe seems like a fairly modest advantage of the
traditional system. I have never used the new system, but this part
of the translation should be simple: if a plot() is called, set the
current viewport. emulation done. (if the user has issued a plot()
and then screws around with the viewport, R could complain and tell
the user that she is now on her own.) I am probably way too naive
here. there must be a lot trickier stuff.
* R regularly makes small changes that break old R code in order to
improve R. This is good. IMHO, emulating the old graphics system
would not have to be perfect one-to-one.
* when new graphics features are added, there must be duplication of
effort to get it into both graphics systems. would it not be easier
in the long-run to have just one system to maintain?
* grImport and your slides look nice. alas, I am searching for
grImport in your book, and it ain't there. ;-). also, pdf should be
as important as postscript to include these days.
* speed and memory size for graphics are less of an issue now than it
used to be.
sheesh, this almost sounds ungrateful. don't mean to be. thanks to
the R team for having put this graphics together. it really is the
best thing out there. this discrepancy in graphics systems is really
nothing more than a minor nuisance.
