What is ltertools?

A column-key toolkit for stitching decades of ecological field data into one table.

ltertools serves the Long Term Ecological Research network, where the same measurement carries a different column name at every site and in every era. Its core is a column key: begin_key drafts one, harmonize applies it, and the 2.0.0 release added check_key to validate a key and standardize to apply one to a single dataset. Harmonization of files above 5 MB now runs in roughly half the time.

What is OptimalBinningWoE?

OptimalBinningWoE spent two releases auditing a C++ engine that was crashing R sessions.

The package wraps 37 binning algorithms in C++, and the last two releases have been dedicated audits of that engine rather than new functionality. The 1.11.0 runtime audit found a segmentation fault in categorical binning that killed the R session for any predictor with no more levels than max_bins — with the default of five, that covers sex, marital status, region, and education. Earlier releases were CRAN compliance patches.

0.0

A column-key toolkit for stitching decades of ecological field data into one table.

◆ Current state

ltertools serves the Long Term Ecological Research network, where the same measurement carries a different column name at every site and in every era. Its core is a column key: begin_key drafts one, harmonize applies it, and the 2.0.0 release added check_key to validate a key and standardize to apply one to a single dataset. Harmonization of files above 5 MB now runs in roughly half the time.

◆ Where it's heading

Development has moved from breadth to depth. The first year added assorted utilities — temperature conversion, solar day length, a site timeline — while the last two releases have concentrated on the key workflow itself: incremental key expansion, validation, per-dataset application, and speed. A dependency archival forced the removal of the JSON helper, trimming the package back toward that core.

◆ Prediction

The key workflow now has draft, expand, check and apply steps, so the remaining gap is diagnostics on the harmonized output; the entries show no other thread in progress.

OptimalBinningWoE spent two releases auditing a C++ engine that was crashing R sessions.

◆ Current state

The package wraps 37 binning algorithms in C++, and the last two releases have been dedicated audits of that engine rather than new functionality. The 1.11.0 runtime audit found a segmentation fault in categorical binning that killed the R session for any predictor with no more levels than max_bins — with the default of five, that covers sex, marital status, region, and education. Earlier releases were CRAN compliance patches.

◆ Where it's heading

The engineering practice is visibly maturing: a static audit in 1.10.0, then a runtime audit in 1.11.0 driven by address and undefined-behaviour sanitizers, a degenerate-input stress harness, and a golden-output regression suite of roughly 3,200 comparisons, with every fix pinned by a test that fails on the prior version. No public API has changed across either release. The package is buying back trust in results that were silently wrong or unreproducible.

◆ Prediction

With the audit programme apparently complete across both static and runtime passes, the next release is more likely to resume feature work on the binning algorithms than to continue hardening.
