[Rd] postscript bug? (PR#9803)

[s.blomberg1 at uq.edu.au]

postscript() produces files that are not encoded as eps, according to
the standard. Hence, word processors such as OpenOffice and AbiWord do
not recognise the files as eps. See
http://www.postscript.org/FAQs/language/node80.html

The problem is in the first line of the postscript file: The header is
wrong. It should be:

%!PS-Adobe-3.0 EPSF-3.0

whereas postscript() produces:

%!PS-Adobe-3.0

The following code replicates the problem:

x <- rnorm(10)
y <- rnorm(10)
postscript("test.eps")
plot(x,y)
dev.off()

# Now try importing test.eps into your favorite word processor.

# Now edit test.eps and change the header to the correct header above, 
and try importing the file again. Works! (This took me a couple of hours
of hair-pulling to figure out. I sure hope it is a genuine bug. :-) )

Cheers,

Simon.
