Define one or two groups to be compared to all other groups

[SebastianHesse]

I am using complexUpset to compare large groups of genes for overlaps.
For a specific analysis, it would be great if I could define one or two groups (eg groups of disease causing genes) that should be compare to all other groups in the dataframe (columns) .

I found that one way would be to define all intersections with:
eg:
intersections=list(
'Comedy',
'Drama',
c('Comedy', 'Romance'))
But as I have a lot of different groups (>10), this solution would create the need to define a of of different intersections.

Any advise how to solve this elegantly would be much appreciated.

Thank you!

I resolved the issue with simply defining all the comparisons of interest like this:
intersections=list(
c('SCN', "mrn.Up"), # 2
c('SCN', "mrn.Dn"), # 4
c('SCN', "mrn.UpDn")

Thanks for your amazing package!
