goat vs nuggets

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.

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.

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.
