afcharts vs nuggets: 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 nuggets?
A pattern-mining package that keeps making its own search cheaper rather than wider.
nuggets is an R package for searching data for conditional patterns - association rules, contrast patterns, correlations - through its dig*() family. The 2.2.x line has settled into a steady rhythm of making that search faster and more inspectable rather than adding new pattern types. 2.2.3 adds permute(), improves axiom-based filtering in the excluded argument, and attaches a search_stats attribute to every dig*() result, so the cost of a search is now reported alongside its output.

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.
nuggets
5.0INFRA · APIS
A pattern-mining package that keeps making its own search cheaper rather than wider.
◆ Current state
nuggets is an R package for searching data for conditional patterns - association rules, contrast patterns, correlations - through its dig*() family. The 2.2.x line has settled into a steady rhythm of making that search faster and more inspectable rather than adding new pattern types. 2.2.3 adds permute(), improves axiom-based filtering in the excluded argument, and attaches a search_stats attribute to every dig*() result, so the cost of a search is now reported alongside its output.
◆ Where it's heading
The arc since 2.1.0 runs toward a leaner, faster core. Dependencies went first - Shiny moved to Suggests, BH and RcppThread dropped - then the search itself: 2.2.2 brought a sparse bit chain, and 2.2.3 adds condition-prefix handling and caching of conjunction supports. New user-facing surface arrives in small, single-function increments (dig_ancestors(), cluster_associations(), now permute()) rather than in themed releases. The search_stats attribute is the first move toward letting users see why a search was expensive rather than only how long it took.
◆ Prediction
Expect the next release to continue in the same shape - another caching or pruning refinement to the dig*() core plus one or two helper functions. The search_stats attribute is the kind of instrumentation that usually precedes tuning controls, so surfacing knobs for the new prefix and support caches is the plausible follow-up.
