orientation of eps files

This is ghostscript feature, I believe.  See here:

https://www.stat.math.ethz.ch/pipermail/r-devel/2003-October/027759.html

I usually do

setenv GS_OPTIONS "-dAutoRotatePages=/None"

in tcsh.

hello,

i have a problem with the orientation of eps files produced with the 
postscript() command. i have generated some eps files with R using:

postscript(file = filename, horizontal = FALSE, paper = "special", onefile 
= F
ALSE, height = height, width = width, pointsize = pointsize)

now, when i include these eps files into a standard paper document (ie. a4 
paper, portrait orientation) everything is fine.

however, i am now wanting to incorporate the same images into a 
presentation. i am making a pdf file, which for presentation purposes is in 
landscape orientation. i am using latex with the prosper package. images 
are included with \includegraphics{} and a pdf file is generated with 
dvipdf. however, in this case, when i include the eps figures the whole 
page suddenly gets rotated around into portrait. eps files from other 
packages seem to work fine.

there is an example of the problem at 
ftp://chinstrap.nu.ac.za/orientation.pdf.

if you have any ideas as to what might be causing this problem, i would be 
extremely happy to hear them.

best regards,
andrew.
