What is admtools?

The age-depth engine under a small stratigraphy stack, growing one adapter at a time

admtools estimates and manipulates age-depth models, with the generics time_to_strat() and strat_to_time() as the transformation layer a small stratigraphy stack is built on. Since 0.1.0 it has accumulated the S3 vocabulary that work needs — sac for sediment accumulation curves, timelist and stratlist for time- and height-associated data — and then adapters outward: pre_paleoTS for StratPal and paleoTS in 0.4.0, FossilSim taxonomy and fossils objects in 0.5.0, and age-to-time transformation for FossilSim in 0.6.0. Version 0.5.0 also added what it calls basic functionality for depth-depth models alongside the age-depth ones.

What is robscale?

A robust-statistics package rewrote its estimators in SIMD C++ and went to CRAN in two weeks.

robscale computes robust scale and location estimators, and its pitch is speed: 21 to 26 times faster than stats::mad, 37 times faster than stats::IQR on small samples, with comparable margins over robustbase for Qn and Sn. The March 2026 releases took it from a GitHub project to a CRAN package carrying eleven estimators, all with confidence intervals.

The age-depth engine under a small stratigraphy stack, growing one adapter at a time

◆ Current state

admtools estimates and manipulates age-depth models, with the generics time_to_strat() and strat_to_time() as the transformation layer a small stratigraphy stack is built on. Since 0.1.0 it has accumulated the S3 vocabulary that work needs — sac for sediment accumulation curves, timelist and stratlist for time- and height-associated data — and then adapters outward: pre_paleoTS for StratPal and paleoTS in 0.4.0, FossilSim taxonomy and fossils objects in 0.5.0, and age-to-time transformation for FossilSim in 0.6.0. Version 0.5.0 also added what it calls basic functionality for depth-depth models alongside the age-depth ones.

◆ Where it's heading

This package moves in step with StratPal, from the same group: admtools 0.4.0 shipped its pre_paleoTS transformations fifty-seven minutes before StratPal released the class itself, and both took on FossilSim within a month of each other in spring 2025. The pattern is consistent — establish generics, define classes, then connect to whatever package the field already uses. The depth-depth work is the one thread pointing inward rather than outward, and it is still described as basic.

◆ Prediction

Depth-depth models are the obvious thing to finish, since they mirror age-depth machinery the package already has; expect any release here to be shadowed by a matching change in StratPal within weeks either side.

A robust-statistics package rewrote its estimators in SIMD C++ and went to CRAN in two weeks.

◆ Current state

robscale computes robust scale and location estimators, and its pitch is speed: 21 to 26 times faster than stats::mad, 37 times faster than stats::IQR on small samples, with comparable margins over robustbase for Qn and Sn. The March 2026 releases took it from a GitHub project to a CRAN package carrying eleven estimators, all with confidence intervals.

◆ Where it's heading

Three releases in a fortnight walk a clear line: expand the public API, submit to CRAN, then tune. The 0.5.4 work is where that tuning shows, and it is unusually specific about hardware, raising sorting-network thresholds after benchmarking and dropping the AVX-512 path entirely in favour of a shorter AVX2-first dispatch chain. The build-fix lists are long, which is what a package fighting compiler and TBB variation across CRAN's platforms looks like.

◆ Prediction

The dispatch hierarchy has been simplified once already; further releases most likely continue narrowing the SIMD surface and hardening the configure step rather than adding estimators. A new estimator would be the surprise.

Frequently asked questions

What is the difference between admtools and robscale?

They serve adjacent needs but don't currently overlap on shipped themes. admtools and robscale 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 admtools better than robscale?

Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. admtools and robscale are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). For your specific use case, the alternatives sections above list other Infra & APIs products to evaluate alongside.
