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().

What is spsurvey?

spsurvey has spent four years consolidating after its 5.0.0 rewrite rather than adding to it

spsurvey implements design and analysis for spatially balanced environmental survey samples, the GRTS methodology used in large-scale monitoring programs. The 5.0.0 rewrite is the defining event in its history, and everything in this window is aftercare. 5.6.0 in September 2025 finally removed the startup message warning users about that upgrade, several years on.

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.

spsurvey has spent four years consolidating after its 5.0.0 rewrite rather than adding to it

◆ Current state

spsurvey implements design and analysis for spatially balanced environmental survey samples, the GRTS methodology used in large-scale monitoring programs. The 5.0.0 rewrite is the defining event in its history, and everything in this window is aftercare. 5.6.0 in September 2025 finally removed the startup message warning users about that upgrade, several years on.

◆ Where it's heading

The direction is toward standard R idioms and away from bespoke ones. 5.4.0 introduced sp_frame and sp_design classes so plot() and summary() work directly, keeping sp_plot() and sp_summary() only for backwards compatibility; 5.5.0 moved warnings from cat() to message() so they can be suppressed normally, and added adjwgtNR() for non-response weight adjustment. Documentation is being pushed off CRAN onto the package website, with only the Start Here vignette remaining. Release cadence is slow — five releases across roughly four years.

◆ Prediction

With the migration messaging retired and the class system settled, further releases are likely to stay in maintenance and statistical-detail territory. Nothing in the entries suggests another rewrite.
