[R] How to plot more than 3 sets in Venn Diagrams?

[Gabor Grothendieck]

If the data you posted is prototypical of your datasets then note that:

- it has two disconnected components of 1 and 4 sets
- there are only 8 unique rows out of 32
- 5 of these 8 are the regions that contain only the non-intersecting
  portion of each of the 5 sets

> unique(mydata)
   AA CH EA IN MY
1   0  0  0  1  0
2   1  0  0  0  0
4   0  0  0  0  1
8   1  0  0  1  0
14  0  0  1  0  0
21  0  1  0  0  0
24  1  0  1  1  1
37  0  0  1  1  0

Thus these are not very interesting Venn diagrams as they are
quite sparse.  Perhaps you would be better off to represent them 
as bipartite graphs with a node for each row and a node for each 
column with the edges corresponding to the ones.  The RGraphViz 
package (or graphViz, itself, locatable via google) could be used for 
that.
