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.
The following code gives the output as in Figure here but reproduced here, although you have plot(Vstem, doWeights = TRUE, type = "circles") with TRUE weights.
