Arguments
- ped
the pedigree information in data.frame format. Pedigree (req. fields: id, sire, dam, gen, population). This requires complete pedigree information.
- minParentAge
numeric values to set the minimum age in years for an animal to have an offspring. Defaults to 2 years. The check is not performed for animals with missing birth dates.
- maxGestationalPeriod
integer value describing the maximum number of days between conception and birth for the species being analyzed (a conservative upper bound, e.g. 210 for rhesus whose typical gestation is about 165 days). It is used two ways: (1) a sire who exited the colony between conception (birth - maxGestationalPeriod) and birth is still retained as a candidate; and (2) a female who delivered another offspring within maxGestationalPeriod days of the focal birth is excluded as a candidate dam, because a female bears one offspring at a time. The sire check uses presence at conception while the dam check uses presence at birth; this asymmetry is intentional – a sire need only be present to conceive, whereas a dam must be present through the pregnancy to give birth.
