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 git2rdata?

git2rdata keeps sharpening one idea: a data frame that produces a readable git diff.

git2rdata stores data frames as plain text plus a metadata sidecar so that version control sees meaningful line-level diffs instead of binary churn. The recent releases have all pushed on the metadata half of that pair: 0.4.1 added `update_metadata()`, 0.5.1 made arbitrary data frame metadata round-trip through storage, and 0.5.2 adds a `convert` argument that records column conversions in the metadata and reverses them on read.

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.

git2rdata keeps sharpening one idea: a data frame that produces a readable git diff.

◆ Current state

git2rdata stores data frames as plain text plus a metadata sidecar so that version control sees meaningful line-level diffs instead of binary churn. The recent releases have all pushed on the metadata half of that pair: 0.4.1 added `update_metadata()`, 0.5.1 made arbitrary data frame metadata round-trip through storage, and 0.5.2 adds a `convert` argument that records column conversions in the metadata and reverses them on read.

◆ Where it's heading

The file format itself settled years ago — the last breaking change was the 0.2.0 hash rework — and development since has been about what travels alongside the data. Storage decisions that used to be implicit are becoming declarative and recorded: significant digits in 0.5.0, arbitrary attributes in 0.5.1, type conversions in 0.5.2. The other steady thread is determinism, from C-locale sorting through `icuSetCollate()`, because unstable ordering is what turns a one-row change into a whole-file diff.

◆ Prediction

The metadata system has absorbed digits, attributes and conversions in three consecutive releases, so the next likely addition is another storage decision moved into metadata rather than any change to the on-disk format.
