Write the Item Matrix TSV — to_matrix

Mirrors the React webapp's "Export Matrix" button + Python's `RegionResult.to_matrix_tsv()` byte-for-byte.

Usage

to_matrix_tsv(result, path)

# S4 method for class 'RegionResult'
to_matrix_tsv(result, path)

Arguments

result: A [`RegionResult-class`].
path: Destination file path.

Value

Invisibly returns `path`.

Details

Columns: Item, <SetName1>, <SetName2>, ..., Region. Rows: one per item. Iteration order: mask 1..(2^n - 1); within each mask, items in `dataset@item_order`.

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)
to_matrix_tsv(result, tempfile(fileext = ".tsv"))
# \donttest{
result <- analyze(load_sample("dataset_real_cancer_drivers_4"))
to_matrix_tsv(result, tempfile(fileext = ".tsv"))
# }
