afcharts vs exametrika
A side-by-side editorial comparison of afcharts and exametrika — release velocity, themes, recent moves, and the top alternatives to consider.
afcharts vs exametrika: at a glance
What is afcharts?
UK government chart styling in ggplot2, chasing ggplot2 v4 and stretching its palette to five.
afcharts supplies the UK Analysis Function's chart styling for ggplot2, as a theme, colour and fill scales, and a use_afcharts() call that applies the styling globally. Version 0.5.1 extends the sequential palette to five shades so it can carry quintile data such as deprivation bands, renames the na_colour argument to na.value, and adds a reset argument to switch the styling back off. The package began as a first release derived from sgplot and has had three releases in roughly two years.
What is exametrika?
exametrika breaks its own numbers to fix them, and ships the fit statistic nominal data lacked.
exametrika is an R psychometrics package covering IRT, latent class and rank analysis, and biclustering. Version 2.0.0 is a deliberate break: an EM convergence defect inherited from the reference implementation stopped estimation after as little as one cycle while reporting convergence, so every EM-based model in the package now returns different estimates than it did before. The package no longer reproduces the numbers printed in Shojima (2022), and the maintainer says so directly rather than burying it. The deprecation removals promised since 1.15.0 ride along in the same release, and the package title changed to Test Data Engineering.

UK government chart styling in ggplot2, chasing ggplot2 v4 and stretching its palette to five.
◆ Current state
afcharts supplies the UK Analysis Function's chart styling for ggplot2, as a theme, colour and fill scales, and a use_afcharts() call that applies the styling globally. Version 0.5.1 extends the sequential palette to five shades so it can carry quintile data such as deprivation bands, renames the na_colour argument to na.value, and adds a reset argument to switch the styling back off. The package began as a first release derived from sgplot and has had three releases in roughly two years.
◆ Where it's heading
The work splits between palette design and keeping the styling composable. On the design side the sequential palette growing to five shades is driven by a specific reporting need rather than aesthetics, since quintiles are a standard unit in UK official statistics. On the mechanical side, the na.value rename was forced by ggplot2 v4.0.1, theme_af() now respects options set by an earlier use_afcharts() call, and a reset argument acknowledges that global styling needs an off switch. These are the problems a styling package hits once people use it inside larger documents.
◆ Prediction
Expect continued adjustment to ggplot2 v4, since the na.value rename is unlikely to be the only argument affected, and further palette work driven by the reporting formats government analysts actually publish. As a sibling to aftables in the same Analysis Function family, it is likely to keep tracking that guidance rather than setting its own direction.

exametrika breaks its own numbers to fix them, and ships the fit statistic nominal data lacked.
◆ Current state
exametrika is an R psychometrics package covering IRT, latent class and rank analysis, and biclustering. Version 2.0.0 is a deliberate break: an EM convergence defect inherited from the reference implementation stopped estimation after as little as one cycle while reporting convergence, so every EM-based model in the package now returns different estimates than it did before.

The deprecation removals promised since 1.15.0 ride along in the same release, and the package title changed to Test Data Engineering.
◆ Where it's heading
The consolidation arc that ran through 1.14.0 and 1.15.0 has closed, but not the way the audit trail suggested it would. Rather than pausing new modelling work through the cleanup, 2.0.0 pairs the breaking removals with real capability: M2() and add_M2() bring a limited-information fit statistic with a full margin-based index set, order-restricted estimation becomes the default for Ranklustering on the strength of a higher likelihood, and LCA() picks up nominal and rated data. The correctness fixes share one shape - defects that got worse as data got larger, where a 700-respondent dataset silently merged fields and a 40-item test returned no assignments at all. A two-tier test suite now keeps 3,507 tests in CI while CRAN sees a 17-second subset.
◆ Prediction
With the deprecation backlog cleared and the EM core rewritten, the next releases have room to build on M2() - most plausibly extending the margin-based indices to the models that do not yet report them. Whether the R Journal submission that shaped 1.13.1 and 1.14.0 has landed is not visible in these entries.
