coga vs multimark
A side-by-side editorial comparison of coga and multimark — release velocity, themes, recent moves, and the top alternatives to consider.
coga vs multimark: at a glance
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 multimark?
Five years of compiler and CRAN fixes on a capture-recapture package.
multimark fits capture-mark-recapture models for populations sampled with multiple non-invasive marks, including a spatial variant. Nothing in the visible history changes the models. Every recent release responds to something outside the package: a CRAN check, a compiler flag, or an upstream package that stopped exporting a function.

coga
0.0INFRA · APIS
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.
multimark
0.0INFRA · APIS
Five years of compiler and CRAN fixes on a capture-recapture package.
◆ Current state
multimark fits capture-mark-recapture models for populations sampled with multiple non-invasive marks, including a spatial variant. Nothing in the visible history changes the models. Every recent release responds to something outside the package: a CRAN check, a compiler flag, or an upstream package that stopped exporting a function.
◆ Where it's heading
This is preservation rather than development. The one substantive entry, in 2021, corrected an MCMC error in multimarkClosedSCR() serious enough that the author told users to revisit past analyses; everything since has been keeping the C code compiling across platforms. Release intervals now stretch to years.
◆ Prediction
Expect the pattern to hold, with a release whenever a toolchain or upstream dependency forces one and no change to the samplers.

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