alifestd_make_ancestor_id_col_polars

alifestd_make_ancestor_id_col_polars(ids: Series, ancestor_lists: Series) → Series

Translate ancestor ids from a column of singleton `ancestor_list`s into a pure-integer series representation.

Each organism must have one or zero ancestors (i.e., asexual data). In the returned series, ancestor id will be assigned to own id for no-ancestor organisms.
