Unpredictable EPS->PDF rotation (PR#4460)

Dear r-bugs,
When I create EPS files, they sometimes appear rotated in my LaTeX PDF
document and sometimes they don't. Two examples:
## x1.eps is not rotated in LaTeX
x <- seq(-1, 1, length=100)
postscript("c:/x1.eps", height=3, width=4,
horizontal=FALSE, onefile=FALSE, paper="special")
plot(x, dnorm(x), type="l")
dev.off()
## x2.eps is not rotated in LaTeX
x <- seq(-2, 2, length=100)
postscript("c:/x2.eps", height=3, width=4,
horizontal=FALSE, onefile=FALSE, paper="special")
plot(x, dnorm(x), type="l")
dev.off()
By LaTeX PDF, I am referring to the dvips->ghostscript pathway, but x2.eps
also rotates when distilled into PDF outside LaTeX. I have tried
ghostscript and acrobat, placed on a page or cropped, so the problem does
not seem to be confounded with particular PDF distillation software.
I'm aware of the pdf() device in R, but EPS files are a widely used format
to share scientific graphics, often winding up embedded in a PDF document
at a later point in the hands of an editor.
If at all possible, a more predictable postscript generator would be
appreciated, where EPS figures would not rotate when embedded in PDF
documents.
I think this is nothing to do with R, which generates predictable postscript for me.
I can reproduce the effect on RedHat 8, but I'm at a loss as to
Perhaps you could tells us what the effect is (the original message says neither is rotated!) and how exactly to reproduce it? I found that x1.eps is not rotated by Distiller, but x2.eps is. That's not a bug but intentional: Distiller (on its default settings) does auto-rotate individual pages of eps files. My guess is that gs is doing something similar on your setup -- it rotates for me under gs8.00 unless I set AutoRotate to /None (I used Convert in GSView to do so).
explain it. The headers and bounding boxes of the two .eps files are identical and to the best of my eyesight they are also using the same coordinate system.
