Here's an example. I usually receive daily updates, so I will post
this directly to the list.
Thanks much: cannot test much more today, as I must prepare the
poster and the talk
and finish the report by Saturday PM (a common story, no doubt). I
will try to imitate
the reply format.
I will mail a PNG of the example directly to Steve if possible.
Notes from a Word 2004 session which I have captured into a PNG.
Printing gives similar results. As I mentioned, Word is useful in
capturing
exploratory sessions which are not suitable for finished code and a
source(file.R)
> quartz()
> plot(c(1,2,3,4,5),(c(1,2,3,4,5))^2)
Copy/Paste to Preview, then Copy/Paste to Word (2004)
Also: Copy/Paste to Preview, then Copy/Paste to GraphicConverter
{ALL BLACK FIELD}
Insert Picture to Word (2005) from PDF saved from Preview:
{CORRECT DISPLAY }
> library(fields)
> quartz()
> x<- 1:10; y<- 1:15; z<- outer( x,y,"+")
> image.plot(x,y,z)
> points( 5:12, 5:12, pch="X", cex=3) # example from image.plot page
Copy/Paste to Preview, then Copy/Paste to Word (2004)
Similar results: Copy/Paste to Preview, then Copy/Paste to
GraphicConverter v 5.5.2
{ALL BLACK O UTSIDE AXES, CORRECT INSIDE. X's show}
Similar results with image(x,y,z) (I know itÂ’s not same usage).

I am referring to Sections 7.2 and 7.3 of the "R for Mac OS X FAQ"
which implies a difference in the quality of the PDF's presented.
Presumably the same fundamentals are allowed, but different graphics
engines perform with different skill. For example, I find that
gs frequently gives less-desirable images.
Microsoft Word 2004 for Mac seems to import PDF's OK, and so does
PowerPoint 2004. I just tested these.
They seem to give identical results, although I believe
that Word is inclined to translate to Windows Bitmap Format at the
slightest provocation (usually a bad idea). I have had some
difficulty with PowerPoint and pdf's in previous years.
Thanks, Bob C
