biocro vs fairmodels
A side-by-side editorial comparison of biocro and fairmodels — release velocity, themes, recent moves, and the top alternatives to consider.
biocro vs fairmodels: at a glance
What is biocro?
BioCro swapped an unstable iteration for real root finders, changing what its crop models compute.
BioCro is a C++ crop growth simulator with an R interface, built from swappable modules for photosynthesis, respiration and development. Version 3.3.0 added multidimensional and one-dimensional root finders to the C++ source and put them to work immediately, replacing the fixed-point iteration used for intercellular CO2 with a Dekker root finder on the grounds that fixed-point iteration is known to be unstable there. Getting to that release also required moving from C++11 to C++17 and updating the bundled boost from 1.71 to 1.89.
What is fairmodels?
fairmodels sits dormant for three years, resurfacing only to satisfy a CRAN check.
fairmodels audits classification models for bias, built around fairness_check() and parity-loss metrics on top of DALEX explainers. The last substantive work dates from 2021; the 2025 release is a single-line change swapping ifelse for if/else in fairness_heatmap. Version 0.2.2 set the package's core design when it superseded metric differences with ratios.

◆ Current state
BioCro is a C++ crop growth simulator with an R interface, built from swappable modules for photosynthesis, respiration and development. Version 3.3.0 added multidimensional and one-dimensional root finders to the C++ source and put them to work immediately, replacing the fixed-point iteration used for intercellular CO2 with a Dekker root finder on the grounds that fixed-point iteration is known to be unstable there. Getting to that release also required moving from C++11 to C++17 and updating the bundled boost from 1.71 to 1.89.
◆ Where it's heading
Two threads run together: the biology is being broken into finer interchangeable modules — separate maintenance respiration, alternative linear and logistic SLA methods, a direct development-index module — while the numerics underneath are being made solvable in general. The root finders are explicitly staged to move into the shared biocro/framework repository, so this is groundwork for other models rather than for this package alone.
◆ Prediction
More module-level alternatives that depend on simultaneous-equation solutions are the natural follow-on, and the root finders should migrate out to biocro/framework as the notes state.
fairmodels
0.0ANALYTICS
fairmodels sits dormant for three years, resurfacing only to satisfy a CRAN check.
◆ Current state
fairmodels audits classification models for bias, built around fairness_check() and parity-loss metrics on top of DALEX explainers. The last substantive work dates from 2021; the 2025 release is a single-line change swapping ifelse for if/else in fairness_heatmap. Version 0.2.2 set the package's core design when it superseded metric differences with ratios.
◆ Where it's heading
The release history describes a package that reached its intended shape early and has been custodial since — the gap from August 2022 to October 2025 carries no functional change at all. What movement exists is CRAN-driven: documentation compliance, example runtimes, coding-style notes. The fairness metrics themselves have not changed since the parity_loss corrections of 2020.
◆ Prediction
On this cadence the next release is most likely another CRAN-prompted one-liner rather than new fairness metrics; nothing in these entries points to active development.
