[R] possible win.metafile( ) problem?

R1.8.0, Win2k:
When I run the code
lset( list( background = list(col = "white")))
xyplot
(
y ~ TIME , data = foo.frame,
scales = list(alternating = FALSE),
ylim = c(.75,y.max),
panel = function(x, y, panel.number, ... )
{
panel.superpose(x = foo.frame$TIME[foo.frame$group == 1],
y = foo.frame$y[foo.frame$group == 1],
subscripts = TRUE,
groups = foo.frame$subject.id[foo.frame$group == 1],
type = 'b',
col = "black",
lwd = 4,
cex = 1.5)
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.
