Hi Johannes,
If you want to display the intersections between your 4 types, you might 
find that intersectDiagram in the plotrix package will serve your 
purpose. It departs from the Venn diagram approach to display an array 
of rectangles, the widths of which are proportional to the number of 
members of each set and intersection.
