splitEnrichment with >2 levels

[jeremymsimon]

Hey @ncborcherding - I have a dataset where there are 3 sample groupings that I'd like to compare. Is it possible to implement something in splitEnrichment that allows for >2 factor levels? It seems to try to plot it, but it is a bit hard to see and it throws a warning. I can use geyserEnrichment instead but it's harder to compare visually across facets. Thanks!
