antaresread vs tglkmeans: at a glance
What is antaresread?
The R reader for Antares Simulator studies, pinned to whatever the simulator ships next
antaresRead loads Antares Simulator studies from disk or the Antares Web API into R. Its release history maps one-to-one onto simulator versions: 2.9.2 for Antares 9.2, 2.9.3 for 9.3, and the 3.0.x line for the study-format changes that followed. The recurring work is the converted study version format (9.0 becoming 900) which has now been fixed or re-fixed in three consecutive releases, and 3.1.0 turns that churn into a declared breaking change as Antares Web 2.33.0 introduces yet another numbering scheme.
What is tglkmeans?
A k-means implementation that just told users their Spearman clustering on missing data was wrong
tglkmeans is a multi-core k-means implementation with seeding, aimed at single-cell and other large matrix workloads. Version 0.4.0 flipped the id_column default and moved to R's random number generator, 0.5.x added count-matrix downsampling and fixed id handling, and 0.6.3 in May 2026 is a correctness release: Spearman distance was ranking missing values as the largest value instead of dropping them, and predict_tgl_kmeans() with Euclidean distance did not reproduce the training metric when a cluster center had a missing dimension.

The R reader for Antares Simulator studies, pinned to whatever the simulator ships next
◆ Current state
antaresRead loads Antares Simulator studies from disk or the Antares Web API into R. Its release history maps one-to-one onto simulator versions: 2.9.2 for Antares 9.2, 2.9.3 for 9.3, and the 3.0.x line for the study-format changes that followed. The recurring work is the converted study version format (9.0 becoming 900) which has now been fixed or re-fixed in three consecutive releases, and 3.1.0 turns that churn into a declared breaking change as Antares Web 2.33.0 introduces yet another numbering scheme.
◆ Where it's heading
The package is a compatibility layer whose roadmap is set entirely upstream, and version identity is where it keeps getting cut. The same .getSimOptionsAPI() version-format fix appears in 3.0.0, 3.0.1 and again in 3.1.0 — three passes at one problem, which suggests the API and disk representations of a study version have not converged. Alongside that, API-mode work is displacing disk-mode work: dedicated endpoints for output listing, district definitions, per-area output handling.
◆ Prediction
The next release will most likely track the following Antares Simulator or Antares Web version, and given the 3.1.0 breaking change, a follow-up correcting the new numbering scheme is a reasonable expectation.
tglkmeans
0.0ANALYTICS
A k-means implementation that just told users their Spearman clustering on missing data was wrong
◆ Current state
tglkmeans is a multi-core k-means implementation with seeding, aimed at single-cell and other large matrix workloads. Version 0.4.0 flipped the id_column default and moved to R's random number generator, 0.5.x added count-matrix downsampling and fixed id handling, and 0.6.3 in May 2026 is a correctness release: Spearman distance was ranking missing values as the largest value instead of dropping them, and predict_tgl_kmeans() with Euclidean distance did not reproduce the training metric when a cluster center had a missing dimension.
◆ Where it's heading
The package handles missing data across three distance metrics, and 0.6.3 shows those paths had drifted apart — Spearman behaved unlike Euclidean and Pearson, and prediction behaved unlike training. Both fixes change results on affected data, and the release notes are careful to bound exactly where: Spearman on data with NAs changes, complete data does not. Performance work runs alongside, with the dense per-thread vote matrix removed from the reassignment step.
◆ Prediction
With the metric paths now aligned on missing-value handling, further work is more likely to target the parallel reassignment internals than the distance semantics.
