What is nuggets?

nuggets keeps compounding on the 2.0 rewrite — more pattern families, lighter install.

nuggets searches for association rules, contrasts and other conditional patterns in the GUHA tradition, with a C++ core behind dig() and an interactive explore() app for reading results. Since the 2.0 rewrite of that core, every release has widened the same three surfaces: more pattern families to mine, more of explore() to inspect them in, and steady performance work underneath. The most recent tag optimises dig() on sparse crisp data with a sparse bit chain and adds clustering characteristics to explore() for association rules.

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.

nuggets keeps compounding on the 2.0 rewrite — more pattern families, lighter install.

◆ Current state

nuggets searches for association rules, contrasts and other conditional patterns in the GUHA tradition, with a C++ core behind dig() and an interactive explore() app for reading results. Since the 2.0 rewrite of that core, every release has widened the same three surfaces: more pattern families to mine, more of explore() to inspect them in, and steady performance work underneath. The most recent tag optimises dig() on sparse crisp data with a sparse bit chain and adds clustering characteristics to explore() for association rules.

◆ Where it's heading

Two forces are shaping the package. One is coverage: baseline, complement and paired-baseline contrasts, correlations, tautologies, ancestors and clustering have all been added as first-class dig_ or explore_ surfaces, so the same search engine now answers a widening set of questions. The other is weight — Shiny packages moved from Imports to Suggests, BH and RcppThread dropped, XSIMD updated, parse_condition() rewritten in C++ — which keeps a package with an interactive app from forcing that app's dependencies on every user. Deprecations are handled through lifecycle rather than removed abruptly.

◆ Prediction

Expect the sparse-data optimisation to extend from crisp to fuzzy data, and explore() to keep gaining tabs as each new pattern family lands, on the roughly six-week cadence the 2.2 line has held.

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.
