[BioC] Venn Diagram for 2, 3 and 4 sets (can be extended for

[Dick Beyer]

Hi Steffan,

I'd be interesting in using your 295 lines of code right away if you'd be willing to send me a copy.

Thanks much,
Dick

Dear all,

I needed Venn Diagrams to accomodate 4 sets rather than the 3 that I got via 
the limma package and I could not find it elsewhere. # Some test data
A<- 1:20
B<- 1:20
C<- 2:20
D<- 3:21

# input gathered into a list, the names
# appear in the diagram
input<-list(a=A,b=B,c=C,d=D)

# calculation of values that should
# go into all the fields
vc <- getVennCounts(input)

# drawing of diagram
drawVennDiagram(vc)

The diagrams look like the ones from limma, i.e., no variation of circle shape 
and to reflect the size of the sets. The only novelty is that is also works on 
4 sets and it is avoiding the use of classes.

What should I do with these 295 lines of code now? It does not seem enough for 
a package on its own. Is anybody interested? Gordon?

Cheers,

Steffen
