Identify all siblings for an individual
Arguments
- x
A gedcom object.
- xref
The xref of an Individual record.
- pedigrees
A character vector of allowed family-child linkages. By default, NULL means all pedigrees (e.g. inc. ADOPTED). If it includes "BIRTH" then this will also pick up non-existent values (since BIRTH is assumed to be the default).
- inc_half
Whether to include siblings that only share one parent.
