prioritizr vs stochvol
A side-by-side editorial comparison of prioritizr and stochvol — release velocity, themes, recent moves, and the top alternatives to consider.
prioritizr vs stochvol: at a glance
What is prioritizr?
Conservation planning absorbs the literature's target-setting rules as code.
prioritizr builds and solves systematic conservation planning problems, handing them to CBC, HiGHS, Gurobi or SYMPHONY. The last two years moved it onto the sf and terra spatial stack and rewrote its internals as R6 classes; the newest release adds a target-setting layer with seventeen named methods from the conservation literature, plus automatic penalty calibration. Solver control parameters and neighbour penalties arrive in the same release.
What is stochvol?
A Bayesian volatility sampler in its maintenance decade, paying for its own speed
stochvol runs MCMC for stochastic volatility models, with a C++ sampler underneath an R interface. Five years of releases in this window contain no new models: the work is compiler and dependency compatibility, CRAN check notes, and a steady trickle of corrections to the sampler itself. Its methodological milestone, the Journal of Statistical Software paper, is recorded in a 2021 tag.

◆ Current state
prioritizr builds and solves systematic conservation planning problems, handing them to CBC, HiGHS, Gurobi or SYMPHONY. The last two years moved it onto the sf and terra spatial stack and rewrote its internals as R6 classes; the newest release adds a target-setting layer with seventeen named methods from the conservation literature, plus automatic penalty calibration. Solver control parameters and neighbour penalties arrive in the same release.
◆ Where it's heading
The package keeps absorbing decisions that used to sit with the analyst. Targets were something you computed and passed in; now add_auto_targets() takes a method specification and the published rules from Jung, Rodrigues, Ward, Watson and Wilson are first-class objects. Penalty values were tuned by hand; calibrate_cohon_penalty() searches for them. The same instinct shows in exporting its validation helpers for other packages to vendor.
◆ Prediction
The deprecation of add_loglinear_targets() in favour of a spec function suggests the older manual target helpers are next to be folded into the same interface.

A Bayesian volatility sampler in its maintenance decade, paying for its own speed
◆ Current state
stochvol runs MCMC for stochastic volatility models, with a C++ sampler underneath an R interface. Five years of releases in this window contain no new models: the work is compiler and dependency compatibility, CRAN check notes, and a steady trickle of corrections to the sampler itself. Its methodological milestone, the Journal of Statistical Software paper, is recorded in a 2021 tag.
◆ Where it's heading
This is what a finished computational package looks like. The formula interface arrived at 3.1.0 and nothing has been added since; what changes is the ground underneath — RcppArmadillo major versions, UBSan checks, error-handling conventions moving from Rf_error to Rcpp::stop for correct memory management. The recurring pattern worth watching is that several releases fix real errors in the sampler's proposal distributions, found by users and by CRAN's own instrumented checks rather than by the maintainer.
◆ Prediction
Nothing in these notes suggests new methodology. Expect the next release when RcppArmadillo or a CRAN check flavour forces one, and treat any bug report against the samplers as the more consequential event.

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