Thank you for your suggestion but unfortunately this won't solve the problem here since I a not using the base graphics and the 'points' function. I am using ggplot which in turn uses Grid for the plotting part. In fact I never even call the point drawing function in Grid to do the plots, it is called when appropriate (e.g. when adding outliers to a boxplot). I could of course modify the source of Grid to plot polygons instead of points and recompile the package but the problem is really in the pdf part (since outputing to SVG draws real circles) so I would rather not tweak the rest to get the pdf right. Thanks anyway.
