No, nothing obvious. If you have an Xfig file - or convert to one from PS, you may be able to extract the lines with their attributes by hand (the file is just text, so you can "see" the vector graphics), and write an R function to plot them (rescaled) onto the device if you need a single graphical element many times. Otherwise, perhaps edit the graphics file after R has completed its work. None of the vector map formats is easy to use for this kind of trick, especially because you probably need attributes on the lines (thickness, colour). > > Cheers, > hinrich d8-) > -- Roger Bivand Economic Geography Section, Department of Economics, Norwegian School of Economics and Business Administration, Breiviksveien 40, N-5045 Bergen, Norway. voice: +47 55 95 93 55; fax +47 55 95 93 93 e-mail: [EMAIL PROTECTED] ______________________________________________ [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
