The 1,072-line vignette attic/vector-valued-functions.Rmd was written, polished over many commits (bibliography, MFPCA case study, registration ladder, quotient-space demo), and then moved to attic. The flagship feature of the current release ships with:
- no long-form documentation
- no NEWS section (only the parenthetical
(now includes tfb_mfpc()) inside the 0.4.2 entry)
- no README mention
Roughly 30 exports and a third of R/ are currently undocumented at the "why would I use this" level.
Fix
- Restore
vignettes/vector-valued-functions.Rmd. If runtime is the concern, precompute the slow fdasrvf chunks via R.rsp precompute or the standard *.Rmd.orig pattern.
- Add NEWS.md section for the next release: "Vector-valued functional data" with subsections covering
tfd_mv/tfb_mv classes, tfb_mfpc() MFPCA, mv registration (method = "srvf_mv", tf_register_shape()), the new geometry verbs (tf_norm, tf_inner, tf_tangent, tf_arclength).
- README.Rmd: a short paragraph + one example. Mention
is_tf() now matches tf_mv too — important for downstream code (this is a silent contract change).
- Update
_pkgdown.yml if needed (cross-checked already by the review — index is complete).
Found in the June-2026 ground-up review. Release blocker.
