You might be encountering the infamous auto-rotation feature. In Unix you can
turn it off via something like
setenv GS_OPTIONS "-dAutoRotatePages=/None"
(or the bash equivalent).

I've generated a version of the classic dotplot of the barley data with

data(barley)
trellis.device("postscript", color=TRUE, file="barley2x3.ps")

trellis.par.set("background", list(col = "white"))

dotplot(variety ~ yield | site, data = barley, groups = year,

xlab = "Barley Yield (bushels/acre)",

It looks fine with gv (though I'd like to make the bounding box
tighter), but when I embed it in a LaTeX slide
(landscape, using seminar package),
\begin{slide}
\includegraphics[,height=.6\textheight]{fig/barley2x3.ps}
\end{slide}
the image is rotated 90 deg CCW. I tried to adjust for this with
\includegraphics[angle=-90,height=.6\textheight]{fig/barley2x3.ps}
but that gives
! Package graphics Error: Division by 0.
What am I doing wrong, or how could I do it differently so it would work?
thanks
