fastrg vs vinecopula: at a glance
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.
What is vinecopula?
Vine copula CDFs arrive; everything else is compile hygiene and boundary fixes.
VineCopula is the long-standing R implementation of vine copula models, maintained alongside Thomas Nagler's kde1d, vinereg, and svines packages over a shared rvinecopulib core. The March 2025 pair is the only recent substance: RVineCDF() for the cumulative distribution of a fitted vine, followed same-day by a Frank-copula tau inversion fix. Everything else in the window is sanity checks, C-loop fixes, and export corrections.

fastrg
0.0ANALYTICS
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.
vinecopula
0.0ANALYTICS
Vine copula CDFs arrive; everything else is compile hygiene and boundary fixes.
◆ Current state
VineCopula is the long-standing R implementation of vine copula models, maintained alongside Thomas Nagler's kde1d, vinereg, and svines packages over a shared rvinecopulib core. The March 2025 pair is the only recent substance: RVineCDF() for the cumulative distribution of a fitted vine, followed same-day by a Frank-copula tau inversion fix. Everything else in the window is sanity checks, C-loop fixes, and export corrections.
◆ Where it's heading
Development has narrowed to filling gaps in the evaluation surface - EmpCDF() in 2.5.0, RVineCDF() in 2.6.0 - while the estimation machinery stays put. Releases arrive in same-day pairs, feature tag then bug-fix tag, so the version count overstates the cadence. A stray v0.2.6 tag with an empty body sits between them and belongs to the shared engine rather than this package's own 2.x numbering.
◆ Prediction
The pattern points to another evaluation-side function rather than new copula families or estimation methods; the run of boundary and NA-handling fixes suggests continued edge-case cleanup in the existing families.
