basicRelationships

<p>A data frame containing kinship and kappa coefficients for some commonly used
relationships.</p>

datasets

Recursive algorithms for computing various relatedness
coefficients, including pairwise kinship, kappa and identity
coefficients. Both autosomal and X-linked coefficients are computed.
Founders are allowed to be inbred, which enables construction of any
given kappa coefficients, as described in Vigeland (2020)
<doi:10.1007/s00285-020-01505-x>. In addition to the standard
coefficients, 'ribd' also computes a range of lesser-known
coefficients, including generalised kinship coefficients, multi-person
coefficients and two-locus coefficients (Vigeland, 2023,
<doi:10.1093/g3journal/jkac326>). Many features of 'ribd' are
available through the online app 'QuickPed' at
