What is pedprobr?

pedprobr is the likelihood engine, and it keeps finding ways to compute what it previously could not.

pedprobr computes pedigree likelihoods for the ped suite. Version 1.1.0 updated its loop handling to match pedtools 2.11.0, including founder and repeated loop breakers, and improved the peeling algorithm with single-child shortcuts and lower memory use. Version 1.0.0 was the other expansion: special lumping lets markers with mutation models that are un-lumpable in the Kemeny-Snell sense be lumped anyway in certain cases, with alleleLimit as a fallback for the rest.

What is ribd?

The pedsuite's coefficient engine: broadening what it computes, then making the plots publishable.

ribd computes relatedness coefficients from pedigrees, covering kinship, inbreeding, kappa, condensed and detailed identity coefficients, and two-locus versions of several of these, in autosomal and X-chromosomal form. The IBD triangle is now drawable in base graphics, ggplot2 or plotly, with an optional inset pedigree, and custom relationships can be placed on it. The most recent release is dominated by correctness work, fixing pair ordering and row alignment in coefficient tables and edge cases for pedigree lists, unrelated individuals and self-pairs.

pedprobr is the likelihood engine, and it keeps finding ways to compute what it previously could not.

◆ Current state

pedprobr computes pedigree likelihoods for the ped suite. Version 1.1.0 updated its loop handling to match pedtools 2.11.0, including founder and repeated loop breakers, and improved the peeling algorithm with single-child shortcuts and lower memory use. Version 1.0.0 was the other expansion: special lumping lets markers with mutation models that are un-lumpable in the Kemeny-Snell sense be lumped anyway in certain cases, with alleleLimit as a fallback for the rest.

◆ Where it's heading

Every significant release here removes a class of computation that used to be infeasible, either by making a marker lumpable or by making a loop breakable. The rest is steady peeling-algorithm optimization, which has been reducing memory footprint release after release since 0.9.2. The newly added .diagnostics option suggests the peeling internals are now complex enough that the maintainer needs to inspect them.

◆ Prediction

Since special lumping is documented as covering only some cases so far, expect further lumping situations to be implemented as pedmut adds them.

2.5

The pedsuite's coefficient engine: broadening what it computes, then making the plots publishable.

◆ Current state

ribd computes relatedness coefficients from pedigrees, covering kinship, inbreeding, kappa, condensed and detailed identity coefficients, and two-locus versions of several of these, in autosomal and X-chromosomal form. The IBD triangle is now drawable in base graphics, ggplot2 or plotly, with an optional inset pedigree, and custom relationships can be placed on it. The most recent release is dominated by correctness work, fixing pair ordering and row alignment in coefficient tables and edge cases for pedigree lists, unrelated individuals and self-pairs.

◆ Where it's heading

The arc runs from generality to presentation to precision. Early releases replaced narrow functions with general ones, most visibly when gKinship() absorbed generalisedKinship() and identityCoefs() superseded the separate autosomal and X-chromosomal identity functions in favour of an Xchrom argument. The middle stretch turned the IBD triangle into a proper plotting surface across three graphics systems. The current phase reads as consolidation, with the newest release listing six bug fixes against four features, several of them alignment errors in output tables, which is where a coefficient library most needs to be exactly right.

◆ Prediction

The two new internal functions in the latest release, inbreedingContributions() and ancestralKinship(), are the kind of thing that surfaces publicly a release or two later, so expect them to become exported decomposition tools. The correctness push through pedigree lists and edge cases suggests the near-term focus stays on hardening rather than new coefficient families.
