splines2 vs vinecopula: at a glance
What is splines2?
Spline bases built to interoperate: periodic B-splines and an nsk-compatible natural basis.
splines2 provides spline basis functions with their derivatives and integrals, in R and through an Rcpp interface. The 0.5.0 release in mid-2023 set the package's current surface; the four releases since are a correctness fix for natural cubic splines with one internal knot, a plotting argument, a compiler warning, and a documentation repair.
What is vinecopula?
Vine copula CDFs arrive; everything else is compile hygiene and boundary fixes.
VineCopula is the long-standing R implementation of vine copula models, maintained alongside Thomas Nagler's kde1d, vinereg, and svines packages over a shared rvinecopulib core. The March 2025 pair is the only recent substance: RVineCDF() for the cumulative distribution of a fitted vine, followed same-day by a Frank-copula tau inversion fix. Everything else in the window is sanity checks, C-loop fixes, and export corrections.

Spline bases built to interoperate: periodic B-splines and an nsk-compatible natural basis.
◆ Current state
splines2 provides spline basis functions with their derivatives and integrals, in R and through an Rcpp interface. The 0.5.0 release in mid-2023 set the package's current surface; the four releases since are a correctness fix for natural cubic splines with one internal knot, a plotting argument, a compiler warning, and a documentation repair.
◆ Where it's heading
The direction is interoperability rather than new mathematics. 0.5.0 added nsk() to match survival::nsk(), an H matrix for converting cubic B-splines produced elsewhere into this package's natural splines, and short aliases meant to be typed inside model formulas. Periodic B-splines were the one genuinely new basis, and its Rcpp knot-sequence handling needed a follow-up fix. Wenjie Wang maintains it alongside intsurv and reda.
◆ Prediction
The last four releases are all corrections, so the next one most likely continues that pattern; a further basis type would break a two-year run of consolidation.

Vine copula CDFs arrive; everything else is compile hygiene and boundary fixes.
◆ Current state
VineCopula is the long-standing R implementation of vine copula models, maintained alongside Thomas Nagler's kde1d, vinereg, and svines packages over a shared rvinecopulib core.

Everything else in the window is sanity checks, C-loop fixes, and export corrections.
◆ Where it's heading
Development has narrowed to filling gaps in the evaluation surface - EmpCDF() in 2.5.0, RVineCDF() in 2.6.0 - while the estimation machinery stays put. Releases arrive in same-day pairs, feature tag then bug-fix tag, so the version count overstates the cadence. A stray v0.2.6 tag with an empty body sits between them and belongs to the shared engine rather than this package's own 2.x numbering.
◆ Prediction
The pattern points to another evaluation-side function rather than new copula families or estimation methods; the run of boundary and NA-handling fixes suggests continued edge-case cleanup in the existing families.
