admtools vs Fiscal: at a glance
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 Fiscal?
UK income tax calculations reach CRAN, then go quiet behind pointer-only release notes.
Fiscal computes UK income tax. It reached its 1.0.0 milestone in March 2026 and shipped two patch releases in the fortnight after, then stopped. The GitHub release bodies carry no changelog of their own: each one points at the NEWS file and the CRAN page, so the feed shows cadence but not content.

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.
Fiscal
0.0INFRA · APIS
UK income tax calculations reach CRAN, then go quiet behind pointer-only release notes.
◆ Current state
Fiscal computes UK income tax. It reached its 1.0.0 milestone in March 2026 and shipped two patch releases in the fortnight after, then stopped. The GitHub release bodies carry no changelog of their own: each one points at the NEWS file and the CRAN page, so the feed shows cadence but not content.
◆ Where it's heading
Three releases in a fifteen-day window reads as post-publication cleanup rather than a development push, which is the normal shape after a first CRAN acceptance. Because every body is the same boilerplate, direction has to be read from the tags alone, and the tags say only that two patches followed the 1.0.0 line.
◆ Prediction
The most likely next release is an annual one tracking a new UK tax year's rates and thresholds. The release notes as published give no evidence for anything beyond that.
