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.

What is projoint?

projoint spent a year on CRAN paperwork, then shipped a correctness fix it flagged itself.

projoint is an R package for analysing conjoint survey experiments, covering Qualtrics import, reshaping, and quantity-of-interest estimation with inter-rater reliability correction. Most of its release history is CRAN admission work — citation formats, DESCRIPTION fields, \value{} tags, vignette cleanups — with four tags backfilled within ninety seconds of each other on 15 July in non-monotonic version order, so neither tag order nor timestamps in this feed track the real sequence. The substantive releases are the ones fixing data-preparation bugs that silently corrupt estimates.

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.

projoint spent a year on CRAN paperwork, then shipped a correctness fix it flagged itself.

◆ Current state

projoint is an R package for analysing conjoint survey experiments, covering Qualtrics import, reshaping, and quantity-of-interest estimation with inter-rater reliability correction. Most of its release history is CRAN admission work — citation formats, DESCRIPTION fields, \value{} tags, vignette cleanups — with four tags backfilled within ninety seconds of each other on 15 July in non-monotonic version order, so neither tag order nor timestamps in this feed track the real sequence. The substantive releases are the ones fixing data-preparation bugs that silently corrupt estimates.

◆ Where it's heading

The maintainer is hardening the path from raw Qualtrics export to estimate, which is where conjoint analysis quietly goes wrong. Three separate releases fix that path: dropped respondent-level weights in organize_data(), repeated-task reshaping in reshape_projoint(), and choice-to-profile mapping in 1.1.3. Each fix now arrives with regression tests and stricter validation rather than just a patch, and 1.1.3 adds an explicit .choice_map so the mapping is auditable instead of inferred.

◆ Prediction

Expect the validation-and-regression-test pattern to keep extending across the import path, with releases continuing to arrive in bursts around CRAN submission rather than on a cadence.
