Thanks for the bug report. I've fixed it by changing the default dpi to 72, and passing res = dpi to the raster devices. However, in light of the fact that most devices don't support dpi, I wonder if using units (like the raster devices) would be more appropriate. Is there any likelihood that the vector devices support will support the units argument in the future? (I also added support for the tiff device, and fixed a severe bug with postscript output) Hadley -- http://had.co.nz/ ______________________________________________ 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.
