c3dr vs goshawk
A side-by-side editorial comparison of c3dr and goshawk — release velocity, themes, recent moves, and the top alternatives to consider.
c3dr vs goshawk: at a glance
What is c3dr?
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.
What is goshawk?
goshawk's release feed is version-bump automation, not product news.
The three most recent tagged releases are all continuous-integration artefacts: a version bump from 0.1.13.9012 to 0.1.14, an action-skipping bump to 0.1.13.9007, and a date-correction commit. None carries a changelog, and the feed has produced nothing since October 2022.

A biomechanics C3D reader graduated through rOpenSci review to CRAN, then learned to write force plates.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
goshawk
0.0ANALYTICS
goshawk's release feed is version-bump automation, not product news.
◆ Current state
The three most recent tagged releases are all continuous-integration artefacts: a version bump from 0.1.13.9012 to 0.1.14, an action-skipping bump to 0.1.13.9007, and a date-correction commit. None carries a changelog, and the feed has produced nothing since October 2022.
◆ Where it's heading
The tags follow the insightsengineering release automation — date-stamped names, [skip vbump] and [skip actions] markers, co-author trailers — which means the substance of any release lives in the package's NEWS file rather than here. On the evidence in this feed the repository is dormant.
◆ Prediction
Nothing in these entries supports a prediction about the package's direction; a meaningful signal would need a release that carries actual notes.
