Thanks, Steve; this works. albeit in a new way.  Some notes for the
user follow.

Simple-documentation copy-paste:
I must start the device this way to avoid difficulties (see quartz())
quartz(bg="white")

Then I may copy and open up the file in Preview;
from there, I may copy again and paste into Word or into
Graphicconverter.  (These probably accepted picts earlier, from
what I could infer from the FAQ).

If one does not set the background, then the Preview version looks
fine, but the image pasted elsewhere has black lettering (usually)
on a black background.

That is likely a bug in whatever program you're pasting it in as it doesn't handle transparency properly (by default the plot is painted on a transparent background so it's easier to adapt it to your style in Keynote etc.). I was checking with Adobe CS2 and it works without problems, so I suspect your application is simply too old to handle that. You don't need to use Preview, you can paste straight from Quartz without problems.


Hence quartz(bg="white")

Higher quality pdf's:
I assume I should do a quartz.save to get a high quality image
if I think that the image may head to publication.

There is no such thing as "higher quality PDFs". All PDFs contain the plot as-is (whether you use copy/paste, quartz PDF output or pdf device). What you probably mean is high quality PNG (bitmap) images. Those can be created with quartz.save by specifying the target resolution such as:
quartz.save("foo.png",dpi=300)
However, that is not what you want to use for publications.

Note that MS products cannot handle PDF (definitely not on the Windows side), so you cannot use PDF there (which is really stupid, but that's another story). That's why you may prefer higher-resolution PNG if the document is to be shared with Windows people.


When I do this, the image opens correctly in Preview, but it appears that some images (a filled-contour color field overlaid by labelled contours in plot4d.r) do not display correctly in my old Adobe application (a second whiting out, maybe?.

Can you, please, share with use the code to reproduce this so we can check it?

Thanks,
Simon




If I do not set bg="white" then both are drawn correctly from the
quartz.save()
version.

regards, Bob

Subject: [R-SIG-Mac] Difficulties with quartz() device and clipboard?
I have difficulties with the R-GUI or the R Quartz Window,

At one time it was easy to copy to the clipboard and then paste into
another document, e.g. Microsoft Word or GraphicConverter or ...
No more.  There is a "Copy" item available (in dark letters, not
greyed)
in the Edit menu, but nothing goes into clipboard. I can verify this
with
several applications that have a "Show Clipboard" menu item.
This was great for recording results of exploratory sessions without
a generating a large number of files.

This might have something to do with what Word is willing to accept.
With Mac OS 10.5.5, R 2.7.2, GUI 1.25 (5217), I can say

 plot(1:10, 1:10, type="l")

R opens a quartz window and displays the line plot.  From there I can
copy the plot to the clipboard (via Cmd-C or Edit > Copy); after the
copy, I'll switch to Preview.app and press Cmd-N ("New from
clipboard") within Preview; Preview creates a new pdf document with
the plot.

Perhaps word doesn't handle pasting of pdf data?


Items saved by quartz.save do not seem to open correctly in Preview
or Acrobat.  I assume that one must close the Quartz device with
dev.off()  Maybe I just need an example of quartz.save in action.)

 plot(1:10, 1:10, type="l")
 quartz.save("foo.png");
 quartz.save("foo.pdf", type="pdf");

After running these three commands, you should have a pdf named
"foo.pdf" and a png named "foo.png".

HTH.
