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. best, /iaw ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
