How to generate a file where we get the list of common Genes expressed in each combination in a venn diagram

Question

[aka]

Hi,

I generate a Venn Diagram and I can generate an access to intersection data with venn() like below:

I would like to get a file for each intersection that gives me the genes of this intersections and their associated line, is there an efficient way to do this? A function, a script? I tried some methods but it's really slow and not efficience, I have a lot of data of this type to retrieve and I would like to optimize.

I can use compare() for two tables but not I have to compare 3 or 4 tables...

Thanks for your help and in advance for your answers,

Have a nice day,
