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 fastrg?

A fast random-graph sampler that spent 0.3.1 fixing what its parameters actually mean.

fastRG samples from generalized random dot product graphs — stochastic blockmodels, degree-corrected and overlapping variants, directed and undirected — in time proportional to the number of edges rather than nodes squared, which is what makes large sparse networks tractable. Since 0.3.1 the model is constructed and parameterised in one object, with sampling methods taking that object rather than re-specifying edge distribution at sample time.

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.

0.0

A fast random-graph sampler that spent 0.3.1 fixing what its parameters actually mean.

◆ Current state

fastRG samples from generalized random dot product graphs — stochastic blockmodels, degree-corrected and overlapping variants, directed and undirected — in time proportional to the number of edges rather than nodes squared, which is what makes large sparse networks tractable. Since 0.3.1 the model is constructed and parameterised in one object, with sampling methods taking that object rather than re-specifying edge distribution at sample time.

◆ Where it's heading

The package's development has been about semantic correctness more than speed. The 0.3.1 release moved edge-distribution arguments to the constructors and reinterpreted the mixing matrix S under Bernoulli parameterisation; 0.3.2 then flipped the meaning of X and Y in directed blockmodels so outgoing and incoming factors match the edge convention, and made block sorting conditional rather than unconditional. Both are corrections to what returned values mean, not to how fast they arrive. The 2025 release is CRAN documentation linking only.

◆ Prediction

With parameterisation settled and only a documentation release since 2023, the package reads as feature-complete for its sampling families. Nothing in the entries points to additional model types being queued.
