Please see the footer of this message. What do you want to be transparent, and what did you use to try to get it (there are many possibilities)? What OS and version of R is this?

Note that the default value of "bg" for the png() and tiff() devices is "white", and the Windows version of the tiff() device does not support transparency. But png(bg="transparent") does give a transparent background.

Hi all,
I'm putting a few plots together and wondering what format would be best to export a few scatter plots to Illustrator to make a figure. I'm thinking about overlaying some plot in Illustrator, so the export file type has to be
transparent for Illustrator (version 10).
I tried PNG and TIFF, but it does not seems to have transparency that is
recognized by Illustrator (or Photoshop for that matter).

EMF (meta data file) on the other hand is very good. The only problem is that every dot on the plot becomes a vector, which slows the program down
considerably (I have about 200k dots on a graph).

So, is there a good way to import these plot in as picture so I can use them
as layer for Illustrator (Photoshop would be fine too).

Thank you all.
