mcmcensemble vs r2dii.plot: at a glance
What is mcmcensemble?
An ensemble sampler just admitted its walkers were barely talking to each other.
mcmcensemble provides affine-invariant ensemble MCMC samplers — differential evolution and stretch move — behind a single MCMCEnsemble() entry point. The API consolidated in 3.0.0 around a flexible inits argument and a hidden internal surface, with parallelism delegated to the future framework. The 2025 release fixed a defect in the sampling behaviour itself, and results now differ from every earlier version.
What is r2dii.plot?
PACTA's climate-alignment charting layer split prep from plotting, then settled into stable.
r2dii.plot renders the standard PACTA climate-alignment charts — trajectory, tech mix, emission intensity — as ggplot2 objects, paired with the 2DII colour palettes and theme. Since 0.4.0 the package has exposed a two-step pipeline where prep_*() shapes the data before plot_*() draws it, while qplot_*() remains the one-call convenience path. It declared itself stable in early 2025.

◆ Current state
mcmcensemble provides affine-invariant ensemble MCMC samplers — differential evolution and stretch move — behind a single MCMCEnsemble() entry point. The API consolidated in 3.0.0 around a flexible inits argument and a hidden internal surface, with parallelism delegated to the future framework. The 2025 release fixed a defect in the sampling behaviour itself, and results now differ from every earlier version.
◆ Where it's heading
Development has moved from packaging to statistics. The early releases were about shape: a rename, argument alignment, moving coda to Suggests, adding tests, then parallel execution and named-vector support. The 3.0.0 release closed the API down to one wrapper and generalised initialisation. What is left, as 3.2.0 shows, is the correctness of the sampler itself — walker correlation, ergodicity checks, and grid artefacts in the differential evolution step were all addressed in a single release, all reported by one contributor. The package is being audited rather than extended.
◆ Prediction
Further sampler-behaviour fixes are the most likely next move, since three separate correctness issues surfaced together in the last release and the package's API has been stable since 3.0.0.
r2dii.plot
0.0ANALYTICS
PACTA's climate-alignment charting layer split prep from plotting, then settled into stable.
◆ Current state
r2dii.plot renders the standard PACTA climate-alignment charts — trajectory, tech mix, emission intensity — as ggplot2 objects, paired with the 2DII colour palettes and theme. Since 0.4.0 the package has exposed a two-step pipeline where prep_*() shapes the data before plot_*() draws it, while qplot_*() remains the one-call convenience path. It declared itself stable in early 2025.
◆ Where it's heading
The package has been converging on a settled contract for years. Early releases chased visual polish and label handling, then 0.2.0 exposed the palette scales as reusable ggplot2 components, and 0.4.0 made the prepared data a first-class artefact rather than something hidden inside a plotting call. Recent releases are documentation and hygiene: a data_dictionary describing every column, definitions filled in, demo datasets renamed to say they are demos. It also moved organisations, from 2DII to RMI-PACTA, and its releases stay pinned to r2dii.analysis and to ggplot2's deprecation schedule.
◆ Prediction
With the lifecycle marked stable and the last two releases confined to dataset naming and documentation, the next release is most likely another ggplot2 compatibility pass or a sibling-package alignment rather than new chart types.
