So I guess the question to be answered by the OP now is what code he
was using and what machine specifics he is working with.
The bottom of my savePlot help page says [Package grDevices version
2.8.1 Index].
Is the difference due to our respective platforms (here Mac 10.5.6,
sessionInfo below) or to a difference in versions?

If you are able to switch to Windows it does seem to be supported
there
on savePlot.
Usage
savePlot(filename = "Rplot",
type = c("wmf", "emf", "png", "jpg", "jpeg", "bmp",
"tif", "tiff", "ps", "eps", "pdf"),
device = dev.cur(),
restoreConsole = TRUE)

Unfortunately your burning desire to use savePlot for this purpose
is not
going to reconfigure the capabilities of that function. Just read
the help
page of savePlot:
savePlot {grDevices}
R Documentation
Save Cairo X11 Plot to FileDescription
Save the current page of a cairo X11() device to a file.
Usage
savePlot(filename = paste("Rplot", type, sep="."), type = c("png",
"jpeg",
"tiff", "bmp"), device = dev.cur())
====
Do you see "ps" or "eps" in the supported types? I do not. Why
would you
expect be a warning not to use a type of device that was not
documented as
possible.
Have you looked at dev.copy or dev.print as a method of getting the
user
choice of screen displayed graphics to an output file?

Thanks for your answer.
Use the postscript device to save .ps or .eps files.
Unfortunatly, I can't. I am using savePlot in a package. Several
graphs
(up to 100) are exported at the same time and I would like the
user to chose
the extension. It is why I need savePlot.
Beside, I did not find any warning again postscript in the help
page for
savePlot. Where did you get this information ? I am using R 2.8.1
Christophe
The help page for savePlot does not suggest that it would be of
any value
in saving plots as postscript files.
?postscript
?Devices
