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 OpenLand?

Land-change analysis in R that has spent six years defending one download link.

OpenLand computes land use and cover change metrics from raster time series, including the full intensity analysis framework of Aldwaik and Pontius. The method surface has not moved since the 1.0.0 release in 2020; the four releases since are entirely about surviving CRAN checks and the fragility of fetching its example dataset from Zenodo. The most recent one stops examples from leaving downloaded data in the user's persistent cache directory.

ltertools vs OpenLand: editorial side-by-side

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.

Land-change analysis in R that has spent six years defending one download link.

◆ Current state

OpenLand computes land use and cover change metrics from raster time series, including the full intensity analysis framework of Aldwaik and Pontius. The method surface has not moved since the 1.0.0 release in 2020; the four releases since are entirely about surviving CRAN checks and the fragility of fetching its example dataset from Zenodo. The most recent one stops examples from leaving downloaded data in the user's persistent cache directory.

◆ Where it's heading

Two forces shape every release here: an external data dependency the package cannot control, and upstream churn in the tidyverse. The Zenodo-hosted SaoLourencoBasin dataset has now been the subject of three separate releases — failing gracefully when unreachable, loading through a helper with informative errors, and finally writing to temporary files instead of the cache. The other recurring cost is dplyr, most recently the removal of dplyr::changes() forcing a global-variable declaration. Actual analytical work is rare: the one substantive fix in the window was a memory allocation failure in contingencyTable() on rasters spanning many years or large areas.

◆ Prediction

The entries give no sign of new metrics or methods in progress, so the next release will most likely be another compatibility or CRAN-check response rather than a feature.
