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 vimp?

Algorithm-agnostic variable importance, settled since 2022 and now answering CRAN checks

vimp performs inference on variable importance measures that do not depend on the fitting algorithm, using sample-splitting so tests stay valid under the zero-importance null. The statistical design settled in 2022: predictiveness measures gained their own S3 class, point estimation was decoupled from inference through the final_point_estimate argument, and method and family moved to the outer functions so binary outcomes work. The two 2025 releases are a CRAN documentation fix and an edge-case correction for cutoff-based measures when every prediction is the same value.

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.

Algorithm-agnostic variable importance, settled since 2022 and now answering CRAN checks

◆ Current state

vimp performs inference on variable importance measures that do not depend on the fitting algorithm, using sample-splitting so tests stay valid under the zero-importance null. The statistical design settled in 2022: predictiveness measures gained their own S3 class, point estimation was decoupled from inference through the final_point_estimate argument, and method and family moved to the outer functions so binary outcomes work. The two 2025 releases are a CRAN documentation fix and an edge-case correction for cutoff-based measures when every prediction is the same value.

◆ Where it's heading

Substantive development ended in 2022, followed by one narrow addition — a cluster bootstrap for correlated data in 2023 — and two housekeeping releases. What remains visible are careful decisions about the boundary between estimation and inference, including the warning that a Wald interval will not be centred on the point estimate when the full-data or averaged option is used. The maintainer is keeping the package correct and installable rather than extending it.

◆ Prediction

Expect maintenance releases keyed to CRAN check changes; new predictiveness measures are the plausible extension, since the S3 class added in 2.3.0 was introduced specifically to make adding them simpler.
