Vennerable provides Venn diagrams in R. It displays Venn and Euler diagrams for up to 9 different sets and using a variety of geometries. It allows the display of area-weighted Venn diagrams and allows fine graphical control over the result.
I'm finding this package very useful. One thing I haven't been able to figure out is how to easily specify specific colors for each circle (or shape) outline and fill and how to use alpha transparency instead of uniquely coloring each overlapping segment.
Would it be possible to post an example of doing this for a 3-circle venn-diagram with red, green and blue semi-transparent circles (with matching outlines)?

Thanks so much, Ricardo
