Prof Ripley, I see that now; I can get the transparency to work, but even with using pdf() my plot still does not draw if I first use:
grid.picture(noaalogo,distort=**FALSE,width=0.5,x=0.50,y=0.50) grid.rect(gp=gpar(fill=rgb(1,**1,1,0.9))) Regards, Tom On Fri, Dec 28, 2012 at 1:55 PM, Prof Brian Ripley <rip...@stats.ox.ac.uk>wrote: > I suspect you need a device supporting translucency: PostScript does not > and hence postscript() cannot.
