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.

What is rgm?

A microbiome network model that got itself un-archived by deleting the dependency that killed it.

rgm implements the random graphical model for microbiome interactions across related environments, published in JABES in 2026. The package was archived from CRAN in February 2026 because of its dependency on huge; the recovery release drops that dependency entirely, which cost it the graphical-lasso warm start that used to seed the initial graph — the default is now an empty graph, with warm starts left to the user. A post-processing function returning ggplot diagnostics arrived in the same release.

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.

0.0

A microbiome network model that got itself un-archived by deleting the dependency that killed it.

◆ Current state

rgm implements the random graphical model for microbiome interactions across related environments, published in JABES in 2026. The package was archived from CRAN in February 2026 because of its dependency on huge; the recovery release drops that dependency entirely, which cost it the graphical-lasso warm start that used to seed the initial graph — the default is now an empty graph, with warm starts left to the user. A post-processing function returning ggplot diagnostics arrived in the same release.

◆ Where it's heading

Three tags shipped inside two hours on one day, and the notes are candid about why: 1.1.0 held the actual work but was never released, 1.2.0 restated it under a higher version to signal the size of the change, and 1.2.1 answered CRAN pre-test feedback. Beyond the archival recovery, the visible work is housekeeping that had accumulated — a shadowed rmvnorm() definition, roxygen import tags that were silently emitting nothing, leftover C++ template scaffolding, and build artifacts under version control. The diagnostics function is the only genuinely new user-facing capability in the window.

◆ Prediction

The immediate task was restoring availability, and that is done; the open question the entries raise is whether losing the graphical-lasso warm start affects convergence in practice, which the new diagnostic plots are positioned to answer.
