R Documentation

Effective hypergeometric universe size for a RegionResult

Description

Returns the universe N consistent with the web tool. Binary CSV/TSV datasets get 'dataset@universe_size' (= csv.rows.length, includes all-zero rows); aggregated/GMT/GMX datasets fall back to 'length(item_order)' (= |union of items|).

Usage

effective_universe(result)

## S4 method for signature 'RegionResult'
effective_universe(result)

Arguments

result

A ['RegionResult-class'].

Value

Integer, the universe size N.

Examples

ds <- methods::new("VennDataset",
    set_names = c("A", "B"),
    items = list(A = c("x", "y"), B = c("y", "z")),
    item_order = c("x", "y", "z"),
    universe_size = 10L, source_path = NULL, format = "csv")
result <- analyze(ds)
effective_universe(result)

ds <- load_sample("dataset_real_cancer_drivers_4")
result <- analyze(ds)
effective_universe(result)   # 20000 for binary cancer drivers sample
