eiaapi vs splines2: at a glance
What is eiaapi?
A thin EIA energy-data client whose whole story is making bulk queries survive the API's limits.
eiaapi wraps the US Energy Information Administration API: eia_get() issues a single query, and eia_backfill() decomposes a large date range into chunks the API will actually serve. Three releases across two years cover the package's entire history, and the second and third both exist because of eia_backfill().
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.

eiaapi
0.0ANALYTICS
A thin EIA energy-data client whose whole story is making bulk queries survive the API's limits.
◆ Current state
eiaapi wraps the US Energy Information Administration API: eia_get() issues a single query, and eia_backfill() decomposes a large date range into chunks the API will actually serve. Three releases across two years cover the package's entire history, and the second and third both exist because of eia_backfill().
◆ Where it's heading
The package's development is a single problem being worked: pulling more data than one request allows. Version 0.1.2 introduced eia_backfill() for exactly that, and 0.2.0 fixed it for non-hourly frequencies by adding the frequency and data arguments so it matches eia_get()'s interface and by reworking Date handling. That convergence of the two functions' signatures is the visible design direction — one query idiom regardless of range size.
◆ Prediction
With the two functions now taking aligned arguments, further work most plausibly extends coverage to more EIA endpoints or response shapes. The entries name no specific target.
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.
