Define Hierarchical Subsets Within a Variable Format

add_subs() creates a structured list of sub-definitions, used to represent child elements under a parent label when building hierarchical formats.

The attributes exhaustive and disjoint describe whether:

the subsets collectively cover the parent category (exhaustive = TRUE), and
the subsets are mutually exclusive (disjoint = TRUE).

The three shorthand variants correspond to the most common combinations:
all_of()/davon() → exhaustive and disjoint
some_of()/darunter() → non-exhaustive but disjoint
some_overlap()/undzwar() → non-exhaustive and overlapping

Usage

add_subs(..., label = NA_character_, exhaustive = TRUE, disjoint = TRUE)

ss(..., label = NA_character_, exhaustive = TRUE, disjoint = TRUE)

ss_all(..., label = "Of which")

ss_some(..., label = "Including")

ss_overlap(..., label = "Such as")

davon(..., label = "Davon")

darunter(..., label = "Darunter")

undzwar(..., label = "Und zwar")

Arguments

...: Elements to include as subset definition. Each element is a formula or character string as defined in new_format().
label: Character. A label that should be used for describing the subset in the output table.
exhaustive: Logical. If TRUE, subsets together cover the entire parent category (no elements are excluded). Defaults to TRUE.
disjoint: Logical. If TRUE, subsets are mutually disjoint (no overlap between subsets). Defaults to TRUE.

Value

A list of subset definitions, with attributes subset_type = c(exhaustive = <logical>, disjoint = <logical>) and subset_label = <character>.
