[BioC] Venn Diagram of 4 Sets

[Thomas Hampton]

Thanks very much to Steffan and Thomas.

I have tried  gplots:venn and venndiagram()  and both work.

One question about Dr. Girke's solution  involving
circles for a 4 way Venn.

Aren't there too few areas inside 4 overlapping circles  (13)
to get the 15 areas you need for a 4 way?

Cheers,

Tom
