I've noticed that the postscript files produced by R-0.49
come up inverted in my postscript previewer. Also, they
do not behave like encapsulated postscript files so they
can't be imported into LaTeX documents. If I remove lines
with page-oriented commands like "%%Page", "%%Orientation",
"\bp" and "\ep", the resulting files seem to behave like
legitimate eps files. I've been using the Perl script below
to automate the process:
################################################################
# Perl script to produce encapsulated Postscript-like output
# from R-0.49-produced Postscript files. (Invoke using the name
# of a Postscript file as the argument.)
################################################################
#!/usr/local/bin/perl
open(FILE,"./$ARGV[0]");
while (<FILE>) {
if (!/\%\%Page./ && !/\%\%Orientation./ && !/\/bp/ &&
!/\/ep/ && !/^bp\b/ && !/^ep\b/) {
s/^\%\!PS-Adobe-3.0/\%\!PS-Adobe-3.0 EPSF-3.0/;
print "$_";
}
}
################################################################
Unless I am the only person experiencing problems with postscript
output, I think it would be a worthwhile project to modify the
existing postscript driver to output compliant eps files as an option.
If I had the requisite knowledge of postscript, I would volunteer...

My postscript files come up the right way around in ghostview and import beautifully into LaTeX with \epsfig. They are also in colour (which I have only just worked out how to do in S-PLUS). Most, if not all, of my postscript files were produced by save.plot() rather than by postscript(). This may explain the difference, but they do include the %%Orientation, %%Page, /ep, and so on. Also, in earlier versions of R I used postscript() with no problems. What LaTeX commands and dvi converter are you using? I have used both the NTeX (on Linux) and teTeX versions of LaTeX2e with the dvips converter, and used the epsfig package.
