mcmcensemble vs unhcrthemes
A side-by-side editorial comparison of mcmcensemble and unhcrthemes — release velocity, themes, recent moves, and the top alternatives to consider.
Shared themes:r-package
mcmcensemble vs unhcrthemes: 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 unhcrthemes?
UNHCR's chart theme re-based itself on a new house standard, then lost its font pipeline to CRAN attrition.
unhcrthemes supplies theme_unhcr() and the agency's official palettes to ggplot2 users, making it the mechanism by which UNHCR's visual standards reach analysts' charts. The 2025 releases realigned the theme and palettes to the revised UNHCR Data Visualization Guidelines and then stripped out the extrafont dependency. Lato is now imported through systemfonts only.

An ensemble sampler just admitted its walkers were barely talking to each other.
◆ 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.
unhcrthemes
0.0ANALYTICS
UNHCR's chart theme re-based itself on a new house standard, then lost its font pipeline to CRAN attrition.
◆ Current state
unhcrthemes supplies theme_unhcr() and the agency's official palettes to ggplot2 users, making it the mechanism by which UNHCR's visual standards reach analysts' charts. The 2025 releases realigned the theme and palettes to the revised UNHCR Data Visualization Guidelines and then stripped out the extrafont dependency. Lato is now imported through systemfonts only.
◆ Where it's heading
Two different forces drive this package. The first is institutional: when the agency published 2025 guidelines, the package followed within months, updating text and gridline colours, revising existing palettes and adding new categorical, sequential and diverging ramps, with older colours flagged for eventual removal. The second is defensive — the font stack was rebuilt not by choice but because Rttf2pt1 is leaving CRAN, and the honest release note concedes the cost: embedding the official Lato font in PDFs is no longer possible. A deprecation of the older palettes is already announced.
◆ Prediction
The announced phase-out of deprecated colours is the most likely next release, since the 0.7.0 notes commit to it explicitly; any further font work depends on what systemfonts can offer for PDF embedding.
