So far I used VennDiagram and venneuler packages of R, but the main thing with these two packages is that they do not generate a proportional diagram. Lets say one set has 25 elements (A) and the others (B, C, D) are 10-15. I expect A to have a larger area than the rest. This is not what I am getting.
The other issue is that I have 0s in the diagram. Some of the sets do not have any common elements, so I should not see anything for their overlap. I am seeing 0's for their intersection set (I guess this is because the circles are not proportional). Moreover, one of the sets (C) have all the elements of the largest set (A), so C circle should be inside A circle. This is also not happening.
Any suggestions?
PS: Attached is the venneuler package output. Not really informative as it is.
I think you have some confusion: Despite the fact that A is 25 and C is 16 that does not mean C suppose to be included in A unless there is 16 elements of A are the same 16 element in C, for example A is 1:25 and C is 1:16. I believe this is not the case in your data since B&D=10 and B=15 and D=16. Zeros represents there is no intersection.
See the following code:
