A textbook data package whose whole job is to stay installable, and whose releases prove how much work that is.
A side-by-side editorial comparison of medicalcoder and projoint — release velocity, themes, recent moves, and the top alternatives to consider.
A comorbidity-coding package relicenses to BSD and grows past the American coding systems
medicalcoder maps ICD diagnosis codes to comorbidity conditions using the Charlson, Elixhauser, AHRQ and PCCC method families. Three releases since June 2026 moved it from a US-centric tool to one carrying Australian and Swedish modifications, added four new Charlson variants, and introduced a choice between precomputed code-condition links and regex mapping applied directly to input codes. The license moved from GPL-2 to BSD 3-Clause along the way.
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.

Two things are happening at once. The coding surface is broadening — ICD-10-AM, ICD-10-SE, Swedish register-based and MIMIC-IV-consistent Charlson methods — which points at users outside the US claims-data world. Separately, the package is hardening: validation on encounter ordering, deterministic result ordering, NA rather than NaN for zero counts, and corrected AHRQ and Quan mappings for fiscal years 2023 to 2026. The mapping argument is the first real fork in how the computation runs rather than what it covers.
Regex mapping is currently unavailable for charlson_beyrer2021 and the release notes flag it as a gap, so closing that is the most clearly signposted next step.

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.
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.

nuggets keeps compounding on the 2.0 rewrite — more pattern families, lighter install.
eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.
dqcheckr adds drift analysis, then removes the YAML a user had to hand-write.
