Usually I use base plotting (plot, points) to create symbols that may have colors for the border (col=...) and border (bg=...), but have to further process the graphs in Adobe Illustrator to fine-tune colors, opacity etc.
Unfortunately, R actually draws the border and the fill as two separate shapes on top of each other, which is somewhat difficult to handle if there are many data points.
Is there a way to plot border and fill in a single shape? Or to group these border shapes separately from the fill shapes from within R?
