What is rsofun?

An ecosystem model starts tracking carbon isotopes and land-use change.

rsofun wraps the P-model and BiomeE vegetation models in R with Fortran cores, covering photosynthesis, water balance and forest demography, plus Bayesian calibration. The 5.1.0 release is the first in the window to widen what the models simulate rather than reorganise them. Before it, the history is renaming, cost-function rewrites and output-format consistency work.

What is transltr?

A new R localization package that reached CRAN and immediately downgraded itself to experimental.

transltr is a young package for supporting many languages in R, built around Text and Translator classes. Its entire public history is four release candidates over four weeks in early 2025 — there are no final tags, so the RC is the release event here. Two of the four exist only to satisfy CRAN reviewers.

An ecosystem model starts tracking carbon isotopes and land-use change.

◆ Current state

rsofun wraps the P-model and BiomeE vegetation models in R with Fortran cores, covering photosynthesis, water balance and forest demography, plus Bayesian calibration. The 5.1.0 release is the first in the window to widen what the models simulate rather than reorganise them. Before it, the history is renaming, cost-function rewrites and output-format consistency work.

◆ Where it's heading

The direction is from a calibration harness toward a model that can answer different questions: isotope fractionation now comes out of the P-model, BiomeE handles land use and land-use change, and forcing can be recycled when a simulation outruns its data. Version stamps are unreliable here, with a v5.0 tag carrying only a build fix and predating v4.4, so the arc reads better through content than through numbering.

◆ Prediction

The isotope work is explicitly unfinished, with a constant atmospheric signature standing in for daily d13c forcing, so the next likely step is accepting that as model input.

A new R localization package that reached CRAN and immediately downgraded itself to experimental.

◆ Current state

transltr is a young package for supporting many languages in R, built around Text and Translator classes. Its entire public history is four release candidates over four weeks in early 2025 — there are no final tags, so the RC is the release event here. Two of the four exist only to satisfy CRAN reviewers.

◆ Where it's heading

The arc is unusually candid about instability. The first release shipped with an explicit instruction to treat it as beta until 1.0.0, and 0.1.0 then went further, reverting the package's lifecycle badge from a firmer status back to experimental because the maintainer had broken more than intended — naming the Text and Translator methods as the parts still likely to move. Test coverage is repeatedly cited as the thing holding the package together while the interface is not yet fixed.

◆ Prediction

The self-declared plan is a 1.0.0 that settles the Text and Translator method signatures; until then expect further breaking changes, and the release notes will most likely keep pointing at NEWS.md rather than summarising them.
