I have downloaded results from scopus of papers by doing various queries for each topic. The downloaded singleton papers are identified by EID. I would like to see where the intersections are, i.e., if there are any overlaps (e.g., if those found with query 1 are also found in the cluster found with query 2, etc.) and if there are any overlaps. I would then need to do a pascalTriangle to see the matrix of intersections and then a Venn diagram.
I am attaching figures of the outputs I would need.
I would like to see this method: https://cran.r-project.org/web/packages/eulerr/vignettes/introduction.html. But I have 20 cluster and I am not able to find the intersection. The cluster are from 1 to 10 and I have to find "1&2" = n1, "1&3" = n2 and so on.
