What is OpenRepGrid?

Repertory grids learn which pole is the preferred one — a data-model change, not another plot option.

OpenRepGrid is the R toolkit for repertory grid analysis, the personal-construct-psychology technique of rating elements against bipolar constructs. Releases arrive every few months and the package passed JOSS review in late 2024. The current release, 0.1.18, is the largest in the window: a rebuilt import/export layer and the introduction of construct pole preference into the grid object itself.

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.

Repertory grids learn which pole is the preferred one — a data-model change, not another plot option.

◆ Current state

OpenRepGrid is the R toolkit for repertory grid analysis, the personal-construct-psychology technique of rating elements against bipolar constructs. Releases arrive every few months and the package passed JOSS review in late 2024. The current release, 0.1.18, is the largest in the window: a rebuilt import/export layer and the introduction of construct pole preference into the grid object itself.

◆ Where it's heading

The arc moves from presentation outward to the data model. 0.1.15 and 0.1.17 were about plots, colours, clustering options, and base-R ergonomics — subsetting by element name, cbind, names(). 0.1.18 changes what a grid can hold rather than how it is drawn, and threads that new attribute through import, construction, and analysis in one release. Getting data in and out is clearly the other priority: three dataframe layouts, long and wide Excel, multi-sheet import, workbook export.

◆ Prediction

With preferred poles now representable, the next likely step is analysis built on top of them — ideal-element distance and alignment measures — plus continued expansion of the import formats the package accepts.

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 OpenRepGrid and robscale?

They serve adjacent needs but don't currently overlap on shipped themes. OpenRepGrid 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 OpenRepGrid better than robscale?

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