[R] "Transparent" background in graphics exported as metafiles

[Philippe Grosjean]

Hi,

Under Windows, I am exporting graphs from R (in metafile -emf- format), and
want to combine them using a graphic package. It happens that the background
of the graph is represented by a filled rectangle (with the color given by
bg=...). This is to be expected. However, I find no options to disable this
and produce a graph with transparent background. Does such an option exist?
If not, then this could be a useful addition, because it is tricky to edit
the metafile, ungroup de elements, select the background rectangle, delete
it, regroup all the other elements and save the graph in a graphic pachage
just to get transparent background on the graph... This could be simply
bg=False.
Thanks,

Philippe Grosjean

P.S.: I really appreciate the changes made to exported graphs in R to
correct the bug in MS Word 2000 (some metafiles are not correctly displayed
on screen in Word 2000 for Windows). It is amazing that the R-team find a
workaround for this Micro$oft bug... and in the meanwhile, Micro$oft itself
does nothing. This is another example of the poor service of MS, comparing
to a community of volunteers creating a GPL software!!! Many, many thanks to
all guys that contributed to fix this.
