c3dr vs git2rdata
A side-by-side editorial comparison of c3dr and git2rdata — release velocity, themes, recent moves, and the top alternatives to consider.
c3dr vs git2rdata: 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 git2rdata?
git2rdata keeps sharpening one idea: a data frame that produces a readable git diff.
git2rdata stores data frames as plain text plus a metadata sidecar so that version control sees meaningful line-level diffs instead of binary churn. The recent releases have all pushed on the metadata half of that pair: 0.4.1 added `update_metadata()`, 0.5.1 made arbitrary data frame metadata round-trip through storage, and 0.5.2 adds a `convert` argument that records column conversions in the metadata and reverses them on read.

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.
git2rdata
0.0ANALYTICS
git2rdata keeps sharpening one idea: a data frame that produces a readable git diff.
◆ Current state
git2rdata stores data frames as plain text plus a metadata sidecar so that version control sees meaningful line-level diffs instead of binary churn. The recent releases have all pushed on the metadata half of that pair: 0.4.1 added `update_metadata()`, 0.5.1 made arbitrary data frame metadata round-trip through storage, and 0.5.2 adds a `convert` argument that records column conversions in the metadata and reverses them on read.
◆ Where it's heading
The file format itself settled years ago — the last breaking change was the 0.2.0 hash rework — and development since has been about what travels alongside the data. Storage decisions that used to be implicit are becoming declarative and recorded: significant digits in 0.5.0, arbitrary attributes in 0.5.1, type conversions in 0.5.2. The other steady thread is determinism, from C-locale sorting through `icuSetCollate()`, because unstable ordering is what turns a one-row change into a whole-file diff.
◆ Prediction
The metadata system has absorbed digits, attributes and conversions in three consecutive releases, so the next likely addition is another storage decision moved into metadata rather than any change to the on-disk format.

gMCPLite exists to be gMCP without Java, and its releases guard that boundary rather than extend it.
