piecenikr vs splines2: at a glance
What is piecenikr?
Drops the vendor name for the icehouse standard, and adds a notation parser.
piecenikr draws icehouse-style game pieces for R graphics. The 0.2.1 release deprecates its two Looney-branded entry points in favour of generic icehouse_* names and adds four setup functions for common piece configurations. It also ships icehouse_parser(), which plugs the package into ppn::read_ppn() for portable game notation.
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.

Drops the vendor name for the icehouse standard, and adds a notation parser.
◆ Current state
piecenikr draws icehouse-style game pieces for R graphics. The 0.2.1 release deprecates its two Looney-branded entry points in favour of generic icehouse_* names and adds four setup functions for common piece configurations. It also ships icehouse_parser(), which plugs the package into ppn::read_ppn() for portable game notation.
◆ Where it's heading
The arc runs from a single-vendor drawing helper toward a general renderer for the icehouse piece standard. The two preview releases from 2020 were cosmetic - a colour tweak and the original function set - so almost the whole of the package's current shape arrived in one 2025 release. Naming, colour palette, and the games catalogue all moved together, which reads as a deliberate reset rather than accumulation.
◆ Prediction
With the parser hook in place, the next visible step is more piece setups registered through icehouse_setup_by_name() and icehouse_games(); nothing in these entries points beyond that catalogue.
splines2
0.0ANALYTICS
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.
