quickLR

A thin wrapper around <code>kinshipLR()</code> for the common scenario of testing a pair
of individuals for paternity and/or sibship, against being unrelated.

Forensic applications of pedigree analysis, including
likelihood ratios for relationship testing, general relatedness
inference, marker simulation, and power analysis. 'forrel' is part of
the 'pedsuite', a collection of packages for pedigree analysis,
further described in the book 'Pedigree Analysis in R' (Vigeland,
2021, ISBN:9780128244302). Several functions deal specifically with
power analysis in missing person cases, implementing methods described
in Vigeland et al. (2020) <doi:10.1016/j.fsigen.2020.102376>. Data
import from the 'Familias' software (Egeland et al. (2000)
<doi:10.1016/S0379-0738(00)00147-X>) is supported through the
'pedFamilias' package.

<dl><dt>x</dt>
<dd>A ped object or a list of such.</dd>
<dt>ids</dt>
<dd>A vector of two typed members of <code>x</code>. If not given, the typed
members of <code>x</code> are selected by default, but note that this gives an error
if the number of such individuals is not 2.</dd>

<dd>The hypotheses to be tested (against 'unrelatedness'). Allowed
values are "pat" (=paternity), "sib" (=full siblings), and "half" (=half
siblings). By default, all three are included.</dd></dl>
