Usage

generate_subsets(set, empty = TRUE, self = TRUE)

Arguments

set: A vector including the empty set and the set itself. Default is TRUE.

self: (optional) When self is TRUE, the resulting subset includes the set itself, otherwise the set itself is removed. Default is TRUE.

Value

A list with the subsets
