admiralonco vs fellingdater: at a glance
What is admiralonco?
The oncology ADaM helper is dissolving into admiral core, one deprecation at a time.
admiralonco is the oncology companion to admiral, and it ships response-criteria recipes rather than code: RECIST, iRECIST, IMWG, GCIG and PCWG3 each arrive as a vignette plus an ADaM template. Cadence is one or two releases a year, each adding a criteria vignette. The 1.4.0 release began deprecating most of the package's own exported functions in favour of generic admiral equivalents.
What is fellingdater?
Went from estimating felling dates to doing the crossdating that produces them.
fellingdater estimates when a tree was felled from sapwood measurements, the core inference in dendrochronological dating of timber. Version 1.0.0 passed rOpenSci review with that scope, and the 2024 releases were mostly about the accompanying JOSS paper and user-supplied sapwood datasets. Version 1.2.0 changed the package's remit substantially, adding an entire trs_* family for tree-ring series handling: crossdating with multiple statistical measures, the Hollstein and Baillie-Pilcher t-value transformations, parallel variation percentages, synthetic series generation, and dated-series plotting.

The oncology ADaM helper is dissolving into admiral core, one deprecation at a time.
◆ Current state
admiralonco is the oncology companion to admiral, and it ships response-criteria recipes rather than code: RECIST, iRECIST, IMWG, GCIG and PCWG3 each arrive as a vignette plus an ADaM template. Cadence is one or two releases a year, each adding a criteria vignette. The 1.4.0 release began deprecating most of the package's own exported functions in favour of generic admiral equivalents.
◆ Where it's heading
The package is converging on a documentation-and-templates model: reusable derivation logic moves upstream into admiral, and admiralonco keeps only the oncology-specific know-how. Every release since 1.0.0 has added a criteria vignette rather than new exported functions, and 1.4.1 extends that by making the template set browsable from the Get Started menu. The surface users program against is shrinking while the guidance they read is growing.
◆ Prediction
Expect the deprecation cycle started in 1.4.0 to advance through its warning and error phases across the next one or two releases, with new work arriving as another response-criteria vignette rather than new functions.

Went from estimating felling dates to doing the crossdating that produces them.
◆ Current state
fellingdater estimates when a tree was felled from sapwood measurements, the core inference in dendrochronological dating of timber. Version 1.0.0 passed rOpenSci review with that scope, and the 2024 releases were mostly about the accompanying JOSS paper and user-supplied sapwood datasets. Version 1.2.0 changed the package's remit substantially, adding an entire trs_* family for tree-ring series handling: crossdating with multiple statistical measures, the Hollstein and Baillie-Pilcher t-value transformations, parallel variation percentages, synthetic series generation, and dated-series plotting.
◆ Where it's heading
The package has expanded backwards along the workflow. It began at the last step — given dated series, estimate the felling date — and 1.2.0 added the step before it, establishing those dates by crossdating in the first place. Version 1.2.1 is early polish on that new surface: axis control, non-syntactic column names, encoding safety in read_fh(). The direction is a single package covering the chain from raw ring widths to a felling-date estimate.
◆ Prediction
Expect the trs_* family to keep accumulating polish and additional crossdating statistics, since it is barely a year old and 1.2.1 was already fixing its plotting and top_n behaviour. Whether the two halves of the package get unified into one workflow interface is the open question the entries do not answer.
