[R] Issue with postscript figures using WinAnsi encoding

[Michael Rennie]

Hi there,

I've hit a bump in writing postscript files with special characters in 
the WinAnsi encoding on a windows machine.

Here's some sample code:

###########################################
postscript(file = "test.eps", encoding="WinAnsi.enc",
    width = 3, height = 5.5, onefile = TRUE, horizontal=FALSE, family = 
"sans",
    title = "testfig", fonts = "sans")

plot(1:5, 1:5, ylab = " \211")

dev.off()

#############################################

If I then try to open the above file in GSview, it doesn't work and I 
get all sorts of errors.

I initially thought this might be an issue with ghostscript, but then I 
looked into the .eps file with a text editor, and see this under the 
encoding:

% begin encoding
 /.notdef /.notdef /.notdef /.notdef /.notdef /.notdef /.notdef /.notdef
 /.notdef /.notdef /.notdef /.notdef /.notdef /.notdef /.notdef /.notdef
 /.notdef /.notdef /.notdef /.notdef /.notdef /.notdef /.notdef /.notdef
 /.notdef /.notdef /.notdef /.notdef /.notdef /.notdef /.notdef /.notdef
 /space /exclam /quotedbl /numbersign /dollar /percent /ampersand 
/quoteright
 /parenleft /parenright /asterisk /plus /comma /minus /period /slash

Does this mean there's an issue in R where it's not able to define 
certain characters from WinAnsi into postscript characters or something? 
I'm sort of new to all this, so excuse me if my terminology is inaccurate.

If I use pdf() on the above code, I can open a nice .pdf that works 
nicely. Also, I've successfully generated .eps files without WinAnsi 
encoding that open happily in GSview.

What looks like a potentially related topic in the archives is here:

However, I'm not clear on how I might be able to use this info. to help 
myself.

If anyone can provide any assistance, I would be eternally grateful.

Oh, and I'm using R 2.4.1.

Cheers,

Mike
