Add hybrid parent and type information — add_hybrid

Parses the input_name column from a taxify() result to extract hybrid parent names and classify the hybrid type.

Usage

add_hybrid_info(x)

Arguments

x: A data.frame returned by taxify().

Value

The same data.frame with additional columns:

hybrid_parent_1: First parent (full binomial), NA if not a hybrid formula.
hybrid_parent_2: Second parent (full binomial, abbreviated or omitted genus expanded), NA if not a hybrid formula.
hybrid_parent_1_accepted, hybrid_parent_2_accepted: The accepted name each parent resolves to against the backbone(s) used for x (from the result's metadata), or NA if the parent did not match.
hybrid_parent_1_id, hybrid_parent_2_id: The backbone taxon_id of the accepted taxon each parent resolves to, usable directly with id2name(), or NA if the parent did not match. An unresolved hybrid formula carries NA in the result's own taxon_id (it has no single backbone record); these two columns are where the component IDs live.
hybrid_type: One of "nothogenus", "nothospecies", "formula", or NA if not a hybrid (same value as the hybrid_type column already on a taxify() result).
