Build an Intersection Entry for hd_geom_venn

Creates one entry describing the overlap region between two or more sets. The ids must match the id values used in the corresponding hd_venn_set() calls.

Usage

hd_venn_intersect(ids, value, name = NULL)

Arguments

ids

Character vector of length >= 2 identifying the overlapping sets. E.g. c("A", "B") for the A-B intersection.

value

Numeric. Area / size of the intersection region.

name

Character or NULL. Optional label for the intersection region. Usually left NULL.

Value

A named list suitable for inclusion in the sets argument of hd_geom_venn().

Examples

hd_venn_intersect(c("A", "B"), value = 2)
#> $sets
#> $sets[[1]]
#> [1] "A"
#> 
#> $sets[[2]]
#> [1] "B"
#> 
#> 
#> $value
#> [1] 2
#> 
#> list(sets = list("A", "B"), value = 2)
