pedbuildr vs spsurvey
A side-by-side editorial comparison of pedbuildr and spsurvey — release velocity, themes, recent moves, and the top alternatives to consider.
pedbuildr vs spsurvey: at a glance
What is pedbuildr?
pedbuildr reconstructs pedigrees from DNA, and it just got much faster at the search.
pedbuildr infers pedigree structure from marker data by scoring candidate pedigrees against likelihoods. Version 0.4.0 moved reconstruct() to mirai for parallel likelihood computation, deprecated the old numCores argument, and picked up the improved loop breaking from pedtools and pedprobr, which lets many complex looped pedigrees succeed where they previously failed. buildPeds() also got significantly faster in its default configuration where mating between lineally related individuals is disallowed.
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.

◆ Current state
pedbuildr infers pedigree structure from marker data by scoring candidate pedigrees against likelihoods. Version 0.4.0 moved reconstruct() to mirai for parallel likelihood computation, deprecated the old numCores argument, and picked up the improved loop breaking from pedtools and pedprobr, which lets many complex looped pedigrees succeed where they previously failed. buildPeds() also got significantly faster in its default configuration where mating between lineally related individuals is disallowed.
◆ Where it's heading
The package is bounded by two costs: how many candidate pedigrees it enumerates and how expensive each likelihood is. The recent release attacks both, parallelizing the likelihoods and speeding up enumeration in the common case. The earlier 0.3.0 release worked on the other end, adding inbreeding limits and a proper result class so the output of a large search is manageable. Releases are infrequent, roughly three years apart in this window.
◆ Prediction
Expect the candidate generation side to receive the same attention the likelihood side just did, since search space size is the remaining bound on what pedbuildr can reconstruct.

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.

Frequently asked questions
What is the difference between pedbuildr and spsurvey?
They serve adjacent needs but don't currently overlap on shipped themes. pedbuildr and spsurvey 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 pedbuildr better than spsurvey?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. pedbuildr and spsurvey are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
