Normalize aggregate markers on canonical names (build-time) — normalize_aggregate

Folds every aggregate marker a backbone or enrichment source may use to one canonical form, "<binomial> aggr.", so taxify's matching engine and enrichment join recognize aggregates uniformly regardless of source spelling. Two cases are handled:

a name already carrying a marker (agg., aggr., -agg, s.l., sensu lato, coll. sp.) is rewritten to "<binomial> aggr.";
a name at an aggregate rank (taxon_rank such as "SPECIES AGGREGATE", "AGGR.", "COLL. SP.") that carries no marker gets " aggr." appended.

Exported for the taxifydb build pipeline so the build and runtime sides share one definition.

Usage

normalize_aggregate_name(name, rank = NULL)

Arguments

name: Character vector of canonical names.
rank: Optional character vector of taxon ranks, the same length as name. When supplied, aggregate-rank rows without a marker are suffixed.

Value

name with aggregate markers normalized to " aggr.".
