When I run the code

panel.superpose(x = foo.frame$TIME[foo.frame$group == 0], y = foo.frame$y[foo.frame$group == 0], subscripts = TRUE, groups = foo.frame$subject.id[foo.frame$group == 0], type = 'l', col = gray(.6))
panel.loess(x = foo.frame$TIME, y = foo.frame$y, col = gray(.2), lwd = 3, lty = 5, span = 1/3) } )
I get the desired graph on the screen. Basically, I am trying to display the time course of a set of test subjects, where each of two subsets is displayed in a different color, and a loess smoother is added to the plot for reference.
When I add
trellis.device(postscript, file = "//.../foo_status.ps", color = TRUE)
to the beginning of this little script, upon trying to open the created file with Ghostview/Ghostscript, I get an error dialog box containing the error message in the attached text file and nothing is displayed.
If I change to
trellis.device(win.metafile, file = "//.../foo_status.wmf", width = 8.5, height = 6.25)
I am able to view the created file, but there are unwanted vertical lines drawn at max(foo.frame$TIME). Moreover, MSWord has a hard time rendering this graph in a stable way, as it is constantly redrawing it and freezing my screen. The file is only 35K, so this should not happen. I tried the same scripting options in R1.7.1 with the same results, which leads me to believe that my xyplot(..) code could be in error. OTOH, this is a fairly simple adaptation of some earlier working code and the within-RGui graph appears to be fine and doesn't have the unwanted vertical lines. When I right-click on this graph and try to paste it directly into MSWord, I get the same "screen freeze" issues, and the vertical lines appear in the window.
Any help would be greatly appreciated.
