Prepare Venn data
process_set_data(venn)
process_region_data(venn, sep = "/", specific = TRUE)a tibble
ggVennDiagram, by default, only return the specific subsets of a region. However, sometimes, we want to show all the overlapping items for two or more sets. For example: https://github.com/gaospecial/ggVennDiagram/issues/64 Therefore, we add a 'specific' switch to this function. While 'specific = FALSE', the seperator will be changed from "/" to "~", and all the overlapping items will be returned. This feature is useful in plotting upset plot.
x = list(
A = sample(letters, 8),
B = sample(letters, 8),
C = sample(letters, 8),
D = sample(letters, 8)
)
venn = Venn(x)
