pedFamilias vs pedmut: at a glance
What is pedFamilias?
pedFamilias exists to read one legacy file format, and it has that job nearly finished.
pedFamilias holds the Familias file interoperability code that was split out of forrel, principally readFam() and writeFam(). The visible history is short and narrow: URL paths accepted as input, a deduplicate option for files produced by the Familias DVI module, better handling of extra individuals, and a fallback mutation model when stabilization fails. The most recent release is explicitly maintenance.
What is pedmut?
pedmut turns awkward mutation models into ones the likelihood engine can actually handle.
pedmut builds and transforms the mutation models used in pedigree likelihood calculations. Its recent arc is a toolkit of model transformations: makeReversible() with three methods, makeStationary() replacing the older stabilize(), adjustRate() for tuning overall mutation rate, and lumpMutSpecial() for lumping models that strong lumpability cannot handle. The most recent release is narrow, adding a programmatic output format to getParams().

pedFamilias

pedFamilias exists to read one legacy file format, and it has that job nearly finished.
◆ Current state
pedFamilias holds the Familias file interoperability code that was split out of forrel, principally readFam() and writeFam(). The visible history is short and narrow: URL paths accepted as input, a deduplicate option for files produced by the Familias DVI module, better handling of extra individuals, and a fallback mutation model when stabilization fails. The most recent release is explicitly maintenance.
◆ Where it's heading
This is a package with a bounded remit. The format it parses does not change, so releases arrive only when someone encounters a file it mishandles, and the fixes are correspondingly specific. The interesting movement is upstream instead: forrel finally removed its deprecated readFam() re-export in 1.9.0, completing the split that created this package.
◆ Prediction
Expect continued low-frequency maintenance driven by real-world .fam files rather than any planned feature work.
pedmut
0.0ANALYTICS
pedmut turns awkward mutation models into ones the likelihood engine can actually handle.
◆ Current state
pedmut builds and transforms the mutation models used in pedigree likelihood calculations. Its recent arc is a toolkit of model transformations: makeReversible() with three methods, makeStationary() replacing the older stabilize(), adjustRate() for tuning overall mutation rate, and lumpMutSpecial() for lumping models that strong lumpability cannot handle. The most recent release is narrow, adding a programmatic output format to getParams().
◆ Where it's heading
The consistent goal is making models satisfy the mathematical properties downstream algorithms require. Reversibility, stationarity, and lumpability each unlock something in pedprobr, and the package keeps adding ways to coerce an arbitrary model into having them. lumpMutSpecial() is explicitly incomplete, described as covering only some cases with more possibly to follow, which sets up the main open thread.
◆ Prediction
Expect additional special lumping cases to be implemented, since the package documents the current coverage as partial and pedprobr's likelihood performance depends directly on it.

Frequently asked questions
What is the difference between pedFamilias and pedmut?
Both compete on the same themes — forensic genetics, r packages — within Analytics. pedFamilias and pedmut are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Is pedFamilias better than pedmut?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. pedFamilias and pedmut are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
