IsoriX vs openair: at a glance
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 openair?
Air quality analysis rebuilt on ggplot2, twenty years of lattice plotting dropped in one release.
openair is the reference toolkit for UK and European air quality data analysis, covering import from national monitoring networks, time averaging, polar and trajectory plots, and trend estimation. Version 3.0.0 rewrote every plotting function in ggplot2 and removed lattice, latticeExtra, hexbin, and mapproj from the dependency tree; 3.1.0 followed six weeks later to settle how parameters reach those functions, remapping base and lattice graphics arguments to ggplot2 equivalents with a warning rather than failing outright.

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.
openair
0.0INFRA · APIS
Air quality analysis rebuilt on ggplot2, twenty years of lattice plotting dropped in one release.
◆ Current state
openair is the reference toolkit for UK and European air quality data analysis, covering import from national monitoring networks, time averaging, polar and trajectory plots, and trend estimation. Version 3.0.0 rewrote every plotting function in ggplot2 and removed lattice, latticeExtra, hexbin, and mapproj from the dependency tree; 3.1.0 followed six weeks later to settle how parameters reach those functions, remapping base and lattice graphics arguments to ggplot2 equivalents with a warning rather than failing outright.
◆ Where it's heading
Two threads run through these releases. The first is the rendering migration and its long tail — deprecated arguments rehomed into breakOpts(), graphical parameters standardized on ggplot2 conventions, trajectory projections collapsed from three arguments into a single crs. The second is data access decaying underneath the package: importEurope() now errors for recent years because the database behind it was retired, while importUKAQ() gained automatic source detection and steadily more careful ratification handling. Correctness fixes keep landing in the analytical core too, including a corrected TheilSen intercept and more consistent bin boundaries in multi-period time averaging.
◆ Prediction
The migration is not finished — 3.1.0 is still remapping legacy graphics arguments with warnings — so expect a release that turns those deprecations into removals, and continued churn around European data import while the replacement service settles.
