Oh, that's been an "accident" : They are part of 'sfsmisc' (a small R-code only package you can quickly install and load) and I use them all the time, but really, I've wanted to just use pdf("asp-ex.pdf", height= 3.3, width=10) myplot(y) ## and now view the pdf file in your favorite viewer Martin DE> Thanks DE> David ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
