OK, not that anyone doing statistics actually cares about this post but the internal rules appear to be this: 1) DOCUMENTED - X11 does not create an initial drawing window any larger than 85% of the screen. On my system that's around 10" high on a 19" monitor, so X11(height=10) produces what I'm looking for while anything larger does not. It's fixed at 10". Additionally width=14.2 is about the maximum I can do horizontally. 2) NOT DOCUMENTED (as far as I can tell so far) - If you choose a value in either direction larger than the value that naturally creates an 85% window then X11 scales the plot space to be 85% in one direction and keeps the aspect ratio that you specified. For instance, on my system X11(height=20, width=10) produces a window that is 10" high (85%) and 5" wide. (as per aspect ration of width/height in the invocation) Bye, Mark ______________________________________________ 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.
