fellingdater vs ReLTER: at a glance
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.
What is ReLTER?
An interface to Europe's long-term ecosystem research network that went quiet after 2.0.
ReLTER provides programmatic access to the eLTER network — the European long-term ecosystem research infrastructure — pulling site metadata, datasets and activities from DEIMS-SDR and enriching them with taxonomic resolution via PESI and WORMS and raster layers from European OpenDataScience. Version 1.0.0 consolidated the function surface and passed into rOpenSci review; 1.1.0 addressed the reviewers' feedback and added vignettes and a Docker install path. Version 2.0.0 was tagged in late 2022 with release notes consisting only of a merge commit message, and nothing has shipped since.

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.
ReLTER
0.0ANALYTICS
An interface to Europe's long-term ecosystem research network that went quiet after 2.0.
◆ Current state
ReLTER provides programmatic access to the eLTER network — the European long-term ecosystem research infrastructure — pulling site metadata, datasets and activities from DEIMS-SDR and enriching them with taxonomic resolution via PESI and WORMS and raster layers from European OpenDataScience. Version 1.0.0 consolidated the function surface and passed into rOpenSci review; 1.1.0 addressed the reviewers' feedback and added vignettes and a Docker install path. Version 2.0.0 was tagged in late 2022 with release notes consisting only of a merge commit message, and nothing has shipped since.
◆ Where it's heading
The visible arc runs from a scattered set of getSite* functions to a reviewed, documented package, and then stops. The absence of notes on the 2.0.0 tag makes it impossible to say from this feed what that major version changed, and the three-year silence afterwards is the more informative signal. What the package does remains useful — the eLTER data it wraps has no other R interface — but the release history gives no evidence of active development.
◆ Prediction
Nothing in these entries supports a confident prediction about future releases; the feed shows a major version with no notes followed by silence. Whether the package is dormant or simply publishing releases elsewhere cannot be determined from what is here.
