What is coga?

A gamma-convolution density package that reached completion in 2018 and has coasted since.

coga computes densities, distribution functions and random numbers for convolutions of gamma distributions, with the numerical work in C++ through Rcpp. It has been feature-complete since 1.0.0 in 2018, and every release in the seven years since has been maintenance: a documentation alias for CRAN, a compiler warning, a maintainer email change, and an Rcpp update requiring Rf_error calls to be guarded. The one functional addition in that period, in 1.1.0, was an unexported function added explicitly for research use.

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.

coga vs prioritizr: editorial side-by-side

C
coga
INFRA · APIS
0.0

A gamma-convolution density package that reached completion in 2018 and has coasted since.

◆ Current state

coga computes densities, distribution functions and random numbers for convolutions of gamma distributions, with the numerical work in C++ through Rcpp. It has been feature-complete since 1.0.0 in 2018, and every release in the seven years since has been maintenance: a documentation alias for CRAN, a compiler warning, a maintainer email change, and an Rcpp update requiring Rf_error calls to be guarded. The one functional addition in that period, in 1.1.0, was an unexported function added explicitly for research use.

◆ Where it's heading

This is a finished package being kept alive rather than developed. The releases track external pressure exactly: CRAN documentation requirements, compiler warnings, Rcpp API changes. Its maintenance is visibly shared with smam, the same maintainer's animal-movement package, which received the same email update, the same format-security fix and the same Rcpp guard within a minute or twenty of coga each time. Neither package is being extended; both are being kept installable.

◆ Prediction

Expect nothing but CRAN and toolchain maintenance, arriving whenever Rcpp or R's check requirements change, and arriving alongside smam. There is no signal in these entries of planned functional work.

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.
