kernelshap vs watina
A side-by-side editorial comparison of kernelshap and watina — release velocity, themes, recent moves, and the top alternatives to consider.
kernelshap vs watina: at a glance
What is kernelshap?
kernelshap makes permutation SHAP practical past eight features, then fixes the kernel weights it had wrong.
kernelshap computes model-agnostic SHAP values in R through Kernel SHAP, permutation SHAP and an exact additive explainer. Version 0.8.0 added a sampling permutation-SHAP algorithm with standard errors and early stopping, lifting the practical feature ceiling past what the exact method allows. Version 0.9.0 then corrected a bug in how kernel weights were computed — exact Kernel SHAP now agrees with exact permutation SHAP — and moved parallelism from foreach to doFuture.
What is watina?
A groundwater database client that has started doing the domain analysis too
watina is the R interface to the Watina groundwater monitoring database, and its history is mostly about making data retrieval correct: filter depths guessed conservatively when missing, spatial masking, aggregation methods per observation well, and a long series of fixes to keep the lazy database queries working across dbplyr versions. The most recent release moves past retrieval into interpretation, adding ionic ratio calculation and a Van Wirdum diagram to plot chemistry data.

kernelshap makes permutation SHAP practical past eight features, then fixes the kernel weights it had wrong.
◆ Current state
kernelshap computes model-agnostic SHAP values in R through Kernel SHAP, permutation SHAP and an exact additive explainer. Version 0.8.0 added a sampling permutation-SHAP algorithm with standard errors and early stopping, lifting the practical feature ceiling past what the exact method allows. Version 0.9.0 then corrected a bug in how kernel weights were computed — exact Kernel SHAP now agrees with exact permutation SHAP — and moved parallelism from foreach to doFuture.
◆ Where it's heading
Two concerns drive this package: making exact methods reach further, and being demonstrably right. The first shows in the additive explainer, the optional background dataset and the sampling permutation algorithm; the second in unit tests written against Python's shap, credited fixes from outside contributors, and a willingness to ship a correctness fix that changes numbers people have already published. Speed work runs continuously underneath — direct solves replacing the Moore-Penrose pseudo-inverse, roughly 10% less memory.
◆ Prediction
The 0.6.0 and 0.7.0 notes each promised a stable 1.0.0 that has not arrived; with the weighting bug fixed and parallelism reworked, a 1.0 release is the most plausible next step.

0.0ANALYTICS
A groundwater database client that has started doing the domain analysis too
◆ Current state
watina is the R interface to the Watina groundwater monitoring database, and its history is mostly about making data retrieval correct: filter depths guessed conservatively when missing, spatial masking, aggregation methods per observation well, and a long series of fixes to keep the lazy database queries working across dbplyr versions. The most recent release moves past retrieval into interpretation, adding ionic ratio calculation and a Van Wirdum diagram to plot chemistry data.
◆ Where it's heading
The package is drifting from a database client toward a domain toolkit. Early releases fought the data layer — connection handling moved to inbodb, sorting semantics changed, defunct dbplyr calls worked around. Recent work assumes retrieval is solved and adds hydrochemical analysis on top, along with defensive handling for the physically impossible inputs that analysis exposes, such as zero conductivity in the warehouse.
◆ Prediction
Expect further chemistry analysis and plotting helpers rather than new retrieval functions, since that is where the newest release invested and where the accompanying vignette points.

Frequently asked questions
What is the difference between kernelshap and watina?
They serve adjacent needs but don't currently overlap on shipped themes. kernelshap and watina 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 kernelshap better than watina?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. kernelshap and watina are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
