probleme with savePlot (to eps)

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?
