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 smam?

Animal-movement models in R, where new stochastic processes arrive years apart.

smam fits statistical models of animal movement, covering moving-resting processes with and without measurement error, moving-resting-handling, and moving-moving processes, with simulation, point estimation and variance estimation for each. The last three releases are pure upkeep: guarding Rf_error calls after an Rcpp update, a maintainer email change, and a compiler warning fix. The substantive work in this window is 0.7.0, which added estimate and vcov generics across all fit functions, and 0.6.0, which added the moving-moving process.

Conservation planning absorbs the literature's target-setting rules as code.

◆ 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.

Animal-movement models in R, where new stochastic processes arrive years apart.

◆ Current state

smam fits statistical models of animal movement, covering moving-resting processes with and without measurement error, moving-resting-handling, and moving-moving processes, with simulation, point estimation and variance estimation for each. The last three releases are pure upkeep: guarding Rf_error calls after an Rcpp update, a maintainer email change, and a compiler warning fix. The substantive work in this window is 0.7.0, which added estimate and vcov generics across all fit functions, and 0.6.0, which added the moving-moving process.

◆ Where it's heading

This package grows by adding process models, and it does so rarely. Between the moving-moving process in 2021 and now, the only interface-level change has been the 0.7.0 generics that gave every fit function a common way to retrieve estimates and their covariance, which is consolidation of an accumulated collection rather than expansion of it. The three releases since are entirely reactive to toolchain and CRAN pressure, and they arrive in step with the maintainer's other package coga, which received the same Rcpp guard within twenty minutes on the same day.

◆ Prediction

Expect further releases to be CRAN and Rcpp maintenance unless a new movement process is published, which is what has historically prompted a minor version here. The generics added in 0.7.0 give any future process model a ready-made interface to slot into.
