Hi,
I need some opinion. I would like to use graph that I generate
from R code and save it into word document. Whichformat is better?
pdf, jpeg or tiff?
Not that I have used word for a while myself, but when I did EPS
files were my preferred format for Word docs that were to be printed
or converted to PDF. The only downside is that Word's EPS importer
displays a low resolution bitmap image of the EPS in the document
so things look pretty sketchy on screen. When printed, however,
EPS images will provide top quality. To achieve the same quality
with JPEG or TIFF would require a much larger image file and
consequently a much larger final document.
I still send my Word-using colleagues EPS files for papers we are
writing etc.
?postscript for the options needed to produce correct EPS.

I agree with Gavin about the relative merits of EPS and any bit-mapped
format (such as jpeg or tiff). And also with Tim Gruene's earlier
comment that "MS product are a little ignorant of PostScript and PDF":
not only ignorant, but do not want to know!
However, a further comment about "Word's EPS importer": You will
only see on screen that "low resolution bitmap image of the EPS"
when viewing the Word document IF the EPS file is in fact EPSI,
i.e. it includes a "header" as PostScript Comments in the initial
section which codes that bitmap for "preview" purposes. EPS files,
*as such*, by default do not include this, and then you would only
see on screen the outline box with nothing inside it. (The only
requirement for a PS file to be EPS is the presence in the Comments
of a "%%BoundingBox: ..." line).
There is nothing about this that I can see in '?postscript', and
running a test using
postscript("testEPS.eps")
plot(...)
dev.off()
produced an EPS file with no such EPSI inclusion.
Ted;
There is a paragraph in the postscript help page regarding EPS,
including the advice to use setEPS thusly:
setEPS( horizontal = FALSE, onefile = FALSE, paper = "special")
.... and see if you get any better results. (After such incantations,
I get this as a header.)

I do have eventual access to MSWord but that would mean I needed to
restart, start up Windows, etc. (Not motivated at the moment.)
There are PostScript-handling program suites, such as ghostscript,
which include a facility to convert from EPS to EPSI: in particular,
ghostscript has the command ps2epsi.
