What is openairmaps?

The mapping half of the openair stack, currently dismantling its own static plotting in favour of the parent package.

openairmaps puts openair's air quality analysis onto interactive maps — polar markers on leaflet, trajectory paths and gridded trajectory levels, and popup construction from site metadata. It now requires openair 3.0.0 and R 4.1, and its polar markers are drawn by ggplot2 as a consequence, which brought a theme argument for customising them. The latest release turns off the automatic captions that openair 3.1.0 started adding, and points the remaining static trajectory functions at openair's own implementations.

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.

0.0

The mapping half of the openair stack, currently dismantling its own static plotting in favour of the parent package.

◆ Current state

openairmaps puts openair's air quality analysis onto interactive maps — polar markers on leaflet, trajectory paths and gridded trajectory levels, and popup construction from site metadata. It now requires openair 3.0.0 and R 4.1, and its polar markers are drawn by ggplot2 as a consequence, which brought a theme argument for customising them. The latest release turns off the automatic captions that openair 3.1.0 started adding, and points the remaining static trajectory functions at openair's own implementations.

◆ Where it's heading

This package follows rather than leads. The ggplot2 polar markers, the pipe change, and the R version floor all arrived because the parent package moved first, and the two now ship within hours of each other. The clearer local trend is contraction: the polarMapStatic() family has been removed outright, the static trajectory functions are now thin wrappers around openair equivalents with removal stated as the plan, and argument names keep being retired in favour of openair's. The package is narrowing toward the one thing openair does not do — interactive maps.

◆ Prediction

The static trajectory wrappers are explicitly flagged for removal, so the next significant release should drop them and leave the package purely interactive.

2.5

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.
