Items in the union of the named sets — union_items • vennDiagramLab

Returns items that appear in ANY of the sets listed in `sets`. Equivalent to `unique(c(items_in_A, items_in_B, ...))`.

Usage

union_items(result, sets)

Arguments

result: A [`RegionResult-class`] from [analyze()].
sets: Character vector of set letters (`"A"`, `"B"`, ...) or display names (values from `result@dataset@set_names`). May mix both.

Value

A character vector of item IDs (deduplicated, first-seen order).

Examples

ds <- methods::new("VennDataset",
    set_names = c("A", "B", "C"),
    items = list(A = c("x", "y"), B = c("y", "z"), C = c("z", "w")),
    item_order = c("x", "y", "z", "w"),
    universe_size = 10L, source_path = NULL, format = "csv")
res <- analyze(ds)
union_items(res, c("A", "B"))   # "x", "y", "z"
#> [1] "x" "y" "z"
