ethiodate vs tealeaves
A side-by-side editorial comparison of ethiodate and tealeaves — release velocity, themes, recent moves, and the top alternatives to consider.
ethiodate vs tealeaves: at a glance
What is ethiodate?
The Ethiopian calendar becomes a first-class R date class, ggplot2 axes included.
ethiodate implements the Ethiopian calendar as an R date class. Over three releases it has gone from conversion helpers to something that behaves like a date type: ggplot2 scales and breaks, quarter extraction, and seq() and cut() methods defined for the ethdate class. The most recent release is a robustness fix for summary.ethdate() under R 4.6.0 and later.
What is tealeaves?
A leaf-temperature model that finished its job in 2020 and has stayed finished
tealeaves solves for leaf temperature from an energy balance, using explicit units to keep parameters consistent and modelling lower and upper leaf surfaces separately so sensible and latent heat loss are computed for each. The package reached its current form in 2020 across versions 1.0.2 to 1.0.5, which added direct or functional sky temperature, dplyr 1.0.0 compatibility, and fixes to a parameter-crossing bug that the new sky temperature function had introduced. The only release since, v1.0.6 in July 2022, corrects a name in the citation file, stops parallel evaluation in a vignette and fixes README links.

The Ethiopian calendar becomes a first-class R date class, ggplot2 axes included.
◆ Current state
ethiodate implements the Ethiopian calendar as an R date class. Over three releases it has gone from conversion helpers to something that behaves like a date type: ggplot2 scales and breaks, quarter extraction, and seq() and cut() methods defined for the ethdate class. The most recent release is a robustness fix for summary.ethdate() under R 4.6.0 and later.
◆ Where it's heading
The work follows the standard path for a custom date class in R: get the arithmetic right, then implement the generics the rest of the ecosystem calls, then handle vector recycling and precision. Switching internal storage from integer to double in 0.3.0 is a quiet but load-bearing change, and accepting numeric months widens the input surface. Each release closes another gap between ethdate and Date.
◆ Prediction
Expect the remaining base generics and formatting paths to be filled in, and continued fixes tracking R's own changes. The package is close enough to full coverage that the next releases will mostly be about edge cases.

◆ Current state
tealeaves solves for leaf temperature from an energy balance, using explicit units to keep parameters consistent and modelling lower and upper leaf surfaces separately so sensible and latent heat loss are computed for each.

The only release since, v1.0.6 in July 2022, corrects a name in the citation file, stops parallel evaluation in a vignette and fixes README links.
◆ Where it's heading
This is finished scientific software. The arc runs from a 1.0.0 that already described the full model, through a usability decision in 1.0.1 to accept unitless values and assign units rather than demand them, to a 2020 cluster of compatibility and correctness work around publication. Nothing since has touched the model, and the 2022 release is pure paperwork. Its most instructive entry remains 1.0.5, where a new feature silently produced incorrect parameter crossing and the fix arrived with tests to pin the behaviour.
◆ Prediction
Expect nothing unless a dependency or CRAN check forces a release; on this record any such release will be documentation and packaging rather than a change to the energy balance.
