What is IsoriX?

An isotope geolocation package still recovering from the r-spatial retirement

IsoriX builds isoscapes and assigns organisms to geographic origin from stable isotope data. Its recent history is defined by the October 2023 retirement of the old R spatial stack: version 0.9.1 recoded substantial parts of the package to drop raster and sp, 0.9.2 restored capabilities that migration had broken - saving and reloading IsoriX objects, and plotting ocean masks containing holes - and documented the new plotting calls that replace the old sp.polygons and sp.points idioms. Since then 0.9.3 revised the bundled bat calibration datasets and 0.9.4 moved the documentation off bookdown.org.

What is missSBM?

missSBM returns after four dormant years with a stricter API and a new refinement step.

The package fits stochastic block models to networks with missing data, covering both missing-at-random and informative sampling designs. After a run of releases from 2019 to 2022, the feed goes quiet until this year's 1.1.0, which breaks the control interface, exposes the block split and merge operations as testable instance methods, and adds a node-swap refinement pass that runs after variational convergence.

An isotope geolocation package still recovering from the r-spatial retirement

◆ Current state

IsoriX builds isoscapes and assigns organisms to geographic origin from stable isotope data. Its recent history is defined by the October 2023 retirement of the old R spatial stack: version 0.9.1 recoded substantial parts of the package to drop raster and sp, 0.9.2 restored capabilities that migration had broken - saving and reloading IsoriX objects, and plotting ocean masks containing holes - and documented the new plotting calls that replace the old sp.polygons and sp.points idioms. Since then 0.9.3 revised the bundled bat calibration datasets and 0.9.4 moved the documentation off bookdown.org.

◆ Where it's heading

Two years of the visible history have gone on infrastructure the science did not ask for. The 0.9.1 notes are unusually candid, warning users that the surrounding package landscape was still in flux and that incompatibility bugs were likely to keep surfacing, which 0.9.2 then confirmed. Only in 0.9.3 does domain work reappear: the bat fur isotope values in the calibration and assignment datasets were corrected to align with current keratin reference material normalisation, so results computed against the old datasets are not comparable with new ones.

◆ Prediction

With the spatial migration settled and the documentation rehomed, the next release is more likely to return to isoscape functionality than to infrastructure, though the entries do not name a specific feature.

missSBM returns after four dormant years with a stricter API and a new refinement step.

◆ Current state

The package fits stochastic block models to networks with missing data, covering both missing-at-random and informative sampling designs. After a run of releases from 2019 to 2022, the feed goes quiet until this year's 1.1.0, which breaks the control interface, exposes the block split and merge operations as testable instance methods, and adds a node-swap refinement pass that runs after variational convergence.

◆ Where it's heading

The new release is maintenance-driven in the best sense: it targets the parts of the codebase that were hard to test or easy to misuse. Replacing free-form control lists with a function of named, defaulted arguments turns silent typos into errors, and pulling the exploration logic out of the collection class makes the search algorithm independently testable without changing it. The polish step addresses a known weakness, reaching individually misclassified nodes that split and merge moves cannot fix.

◆ Prediction

Given the gap before this release, the near-term question is whether the cadence resumes at all; the refactoring it contains would support further algorithmic work if it does.
