Adding chemical databases with one hand while public ones close programmatic access with the other.
A side-by-side editorial comparison of c3dr and GSODR — release velocity, themes, recent moves, and the top alternatives to consider.
A biomechanics C3D reader graduated through rOpenSci review to CRAN, then learned to write force plates.
c3dr reads and writes C3D motion-capture files in R, wrapping the EZC3D library. It cleared rOpenSci peer review and moved into the rOpenSci organisation in April 2025, reached CRAN a month later, and shipped force-platform export in c3d_write() in August. Releases are close together and each one has a clear single purpose.
A weather-station data client that broke one return type to hand back distances instead of bare IDs.
GSODR fetches and tidies NOAA Global Surface Summary of the Day weather data for R. The 4.0.0 release made nearest_stations() return a data.table of full station metadata plus distance in kilometres rather than a character vector of station IDs, with a documented one-liner for anyone who only wanted the IDs. Nothing has shipped since March 2024.

The package is filling in the write side of the read/write pair. Reading was in place from the start; 0.2.0 extends c3d_write() to force-platform data on a direct user request, and the accompanying work preserves matrix structure on import and tracks upstream EZC3D changes. The review-era releases hardened validation and error messages, so the current cycle can be spent on capability rather than polish.
Expect further coverage of C3D block types in the writer and continued tracking of EZC3D releases; the changelog gives no signal of analysis features beyond file I/O.

Nothing has shipped since March 2024.
The package is mature and its releases read as upkeep: refreshing the internal ISD history database, dropping dependencies in favour of base and curl, and hardening the download path against station-year combinations that do not exist. The 4.0.0 change fits the same pattern of returning more structure by default rather than making callers query twice.
The most likely next release is another internal station-history refresh; there is no signal of new data sources or analysis features in these entries.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
Both compete on the same themes — ropensci, r-package — within Analytics. c3dr and GSODR are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. c3dr and GSODR are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
