R help - Jul 2005 - problems with submitting an eps-file created in R

Dear all

I've got some problems submitting a manuscript, because I can't manage 
creating the favourable eps-file of a graph created in R. The journal's 
graphic requirements are as followed:
format: eps
width: max. 6 inches
resolution: min. 1000 dpi
supported fonts: Arial, Courier, Helvetica, Symbol, Times, Charcoal, 
Chicago, Geneva, Georgia, Monaco, Zapf, New York

Itried to ways of getting appropriate file:

1.Creating eps-file in R by drawing into a x11-device and then:
/dev.copy2eps(file = "file.eps", onefile = TRUE, paper =
"a4", family =
"Helvetica",  pointsize=1, print.it = FALSE,  fonts =
"Helvetica")

/2. Generating a postscript-file in R with /
//postscript(file = "file.ps", onefile = TRUE, paper = "a4",
family =
"Helvetica", width = 6, height = 2.2, pointsize=1, print.it = FALSE, 
fonts = "Helvetica")/
an trying to convert it in ghostview.

Neither approach brought the favoured result. The error message I got 
from the quality checking program was :

Warning: Document is Missing Non-Standard Font 

One or more non-standard fonts used in this image is not embedded. Standard
fonts are: Arial, Courier, Helvetica, Symbol, Times, Charcoal, Chicago, Geneva,
Georgia, Monaco, Zapf, New York.

In order to repair this problem, save your document with fonts embedded.

Error: Missing Fonts 

Challenge 
One or more linked or used fonts cannot be found. This is caused by
DigitalExpert not being able to locate fonts on your system. All fonts used in
the document must be active or have a defined and valid path so that
DigitalExpert can find them.
 
Solution 
 The only way to repair this problem is to make the fonts available to
DigitalExpert, and then reprocess the files. In order to make fonts active,
either activate them using a font management program, or move them into the
system:fonts folder.



1. Obviously there's a font problem. Helvetica IS installed in my OS 
(windows 2000). Why "DigitalExpert" does not recognize the
"Helvetica"
font as a standard font? I thought the fonts option would embed the 
specified font in the file. Am I right or is there another way to embed 
fonts?
2. Is there a way to set up the resolution of the created ps/eps-file in 
R (until now I did the settings in ghostview)?
3. I did not find particulars about the pointsize option. What is the 
effect of changing the pointsize value?

With best regards
Christian

The ?postscript man page suggests using onefile = FALSE to get an EPSF 
header directly.  It also suggests paper="special", and
horizontal=FALSE.

If that doesn't work, you'll have to ask whoever wrote the quality 
checking program what they're looking for.

You need to read the help for postscript(), which specifically tells you
in the Details section to use:

postscript(..., onefile = FALSE, horizontal = FALSE, paper =
"special")

to generate EPS files.

There is no resolution setting for a postscript file per se, since PS is
a device independent vector based format and the resolution of the
output is dependent upon the target device/viewer. One exception to this
would be the embedding of a bitmapped object in a PS file, but that is
not applicable here.

EPS files do not normally have a resolution.

Most of those are Windows fonts, and not accurately defined.

My guess is that the checkers are not properly aware of Adobe's standards 
and want something other than an EPS file.

Should be onefile=FALSE.

No, the help file explicitly says that it is your responsibility.
EPS files do not normally have fonts embedded, but they do have DSC marks 
telling the enclosing application to do so.

EPS files do not have a resolution.

It's on the help page.
