biocro vs errors
A side-by-side editorial comparison of biocro and errors — release velocity, themes, recent moves, and the top alternatives to consider.
biocro vs errors: 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 errors?
errors keeps making uncertainty print the way each scientific field expects.
errors attaches uncertainty to numeric vectors and propagates it automatically through arithmetic, as part of the r-quantities family alongside units. The propagation core is settled; recent releases concentrate on presentation and integration — PDG rounding rules in 0.4.2, decimal support in parenthesis notation in 0.4.3, and ggplot2 deprecation tracking in 0.4.1 and 0.4.4.

◆ 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.

◆ Current state

◆ Where it's heading
Two threads run through this history. One is formatting convergence: uncertainty has field-specific conventions, and the package has been absorbing them one contributed pull request at a time rather than imposing a single style. The other is keeping the errors class first-class everywhere R users work — vctrs methods for dplyr 1.0, a geom_errors() layer for ggplot2, missing-value and duplicate handling. Both are integration work, which is what a type-extension package mostly is.
◆ Prediction
Expect further formatting conventions to arrive as contributions, following PDG rounding and the decimals option, plus continued upkeep against ggplot2 aesthetic deprecations that have forced two of the last four releases.
