feat_outgroup | R Documentation |
This feature declares an existing population as outgroup. Outgroups are used to determine the ancestral allele in finite sites simulations and are required there. All individuals of the outgroup are ignored when calculating summary statistics. If the outgroup consists of multiple individuals, all positions where the individuals have different alleles are ignored.
feat_outgroup(population, locus_group = "all")
population |
The population that is marked as outgroup. If finite-sites mutation models are used, the last population must be specified as outgroup. |
locus_group |
The loci for which this features is used. Can either be
