ltertools vs wooldridge: at a glance
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 wooldridge?
A textbook data package whose whole job is to stay installable, and whose releases prove how much work that is.
wooldridge ships the datasets from Wooldridge's Introductory Econometrics so students can load any of them with one command. The data has been essentially complete since the 7th-edition sets landed in 1.4-1; every release since has been about keeping the package on CRAN. The most recent tag exists only to re-run roxygen2 so that documentation URL fixes from the previous version actually reached the .Rd files.

ltertools
0.0INFRA · APIS
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.
wooldridge
0.0INFRA · APIS
A textbook data package whose whole job is to stay installable, and whose releases prove how much work that is.
◆ Current state
wooldridge ships the datasets from Wooldridge's Introductory Econometrics so students can load any of them with one command. The data has been essentially complete since the 7th-edition sets landed in 1.4-1; every release since has been about keeping the package on CRAN. The most recent tag exists only to re-run roxygen2 so that documentation URL fixes from the previous version actually reached the .Rd files.
◆ Where it's heading
The maintainer has been systematically shrinking the package's attack surface for years. Dependencies used only for vignette examples were cut after one of them broke its API and triggered a CRAN removal notice; test infrastructure moved from testthat to tinytest and from Travis and AppVeyor to GitHub Actions; datasets were compressed by stripping attributes left over from the Stata imports. The stated goal, written into the 1.4-2 notes, is that this should be the easiest package the maintainer has to look after.
◆ Prediction
Nothing in the recent entries points to new data; the next release will most likely be triggered by another CRAN check failure or by a new edition of the textbook adding datasets.
