What is REDCapR?

The REDCap API client finished its breaking cleanup and settled into CRAN-compliance mode.

REDCapR is a mature R client for the REDCap research data-capture API, and its release stream shows a package that has already made its consequential changes. The last two releases (1.5.0, 1.6.0) exist purely to satisfy CRAN checks — dropping native pipes from non-essential code, keeping examples from touching an external server. The functional surface has been stable since early 2025.

What is robscale?

A robust-statistics package rewrote its estimators in SIMD C++ and went to CRAN in two weeks.

robscale computes robust scale and location estimators, and its pitch is speed: 21 to 26 times faster than stats::mad, 37 times faster than stats::IQR on small samples, with comparable margins over robustbase for Qn and Sn. The March 2026 releases took it from a GitHub project to a CRAN package carrying eleven estimators, all with confidence intervals.

The REDCap API client finished its breaking cleanup and settled into CRAN-compliance mode.

◆ Current state

REDCapR is a mature R client for the REDCap research data-capture API, and its release stream shows a package that has already made its consequential changes. The last two releases (1.5.0, 1.6.0) exist purely to satisfy CRAN checks — dropping native pipes from non-essential code, keeping examples from touching an external server. The functional surface has been stable since early 2025.

◆ Where it's heading

The arc runs from a deliberate interface break in 1.2.0 — read functions returning tibbles, the *_collapsed parameter family deprecated — through 1.4.0 broadening API coverage into REDCap's file repository, and then into pure maintenance. Test infrastructure has been getting more attention than features: a redirection layer so users can point the suite at their own server, a multilevel-model test project. That is the signature of a package whose maintainer is defending stability rather than expanding scope.

◆ Prediction

Expect continued CRAN-compliance releases at roughly quarterly cadence; any new feature work is most likely further coverage of REDCap endpoints the package does not yet wrap, following the file-repository pattern.

A robust-statistics package rewrote its estimators in SIMD C++ and went to CRAN in two weeks.

◆ Current state

robscale computes robust scale and location estimators, and its pitch is speed: 21 to 26 times faster than stats::mad, 37 times faster than stats::IQR on small samples, with comparable margins over robustbase for Qn and Sn. The March 2026 releases took it from a GitHub project to a CRAN package carrying eleven estimators, all with confidence intervals.

◆ Where it's heading

Three releases in a fortnight walk a clear line: expand the public API, submit to CRAN, then tune. The 0.5.4 work is where that tuning shows, and it is unusually specific about hardware, raising sorting-network thresholds after benchmarking and dropping the AVX-512 path entirely in favour of a shorter AVX2-first dispatch chain. The build-fix lists are long, which is what a package fighting compiler and TBB variation across CRAN's platforms looks like.

◆ Prediction

The dispatch hierarchy has been simplified once already; further releases most likely continue narrowing the SIMD surface and hardening the configure step rather than adding estimators. A new estimator would be the surprise.

Frequently asked questions

What is the difference between REDCapR and robscale?

They serve adjacent needs but don't currently overlap on shipped themes. REDCapR and robscale are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.

Is REDCapR better than robscale?

Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. REDCapR and robscale are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
