Thanks to all who offered advice on how to solve a loss of resolution
problem involving ps from R, ps -> eps from Acrobat, and Word.
It appears that this problem will need to be resolved inside R. If I try
to add anything additional (more text, clipart embellishments) to a ps/eps
file (using, say, Adobe Acrobat, PaintShop Pro, Powerpoint, or Adobe
Illustrator), it gets placed as a separate layer in the finished
file. When Adobe exports the file to .eps format it *silently* merges the
layers which ends up muddying the rectangles, ellipses, and text from the
original postscript file with text and clipart added at the second phase of
the graphic editing process. Saving in PNG, TIF, WMF or any other format
*after* adding new information does the same thing, and I haven't yet found
a way around this.
I can solve the text embellishment issue by adding the information at
"design" time using plot.rpart, text.rpart, and locator functions in
conjunction with "fancy" parameter, but the issue of adding clipart
graphics is not one that I've figured out how to solve.
