going via `bitmap' and using the `pdfwrite' type is probably the better idea since in this case `ghostscript` is used for pdf generation which seems over all to generate cleaner/better pdf-output in comparsion to the R internal pdf-device (I believe there was recently some discussion of this on the list?). joerg ______________________________________________ R-help@stat.math.ethz.ch 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.
