The protist reference database keeps widening past the rRNA gene it was built on.
A side-by-side editorial comparison of ggsketch and mmpca — release velocity, themes, recent moves, and the top alternatives to consider.
ggsketch stopped being a line style and became a drawing-medium simulator.
ggsketch is a ggplot2 extension that renders plots as if drawn by hand. Through the 1.x line that meant one thing: roughening outlines and fills with configurable jitter. The 2.0.0 release published in July reframes the package around simulated drawing media — pen, chisel-tip highlighter, airbrush — and simulated paper grounds, with the sketch geoms inheriting whichever medium is set.
Back from CRAN removal under a new maintainer, with the compiled layer rebuilt.
mmpca implements multiple matrix principal component analysis with a compiled GSL backend. The package spent time off CRAN, and its recent history is a rescue operation rather than a feature program: a new maintainer took it over, moved the native build path onto RcppGSL, and folded the hand-written C bindings into Rcpp. The two most recent entries landed the same day, one restoring the package and one clearing residual CRAN comments.

The maintainer states 2.0.0 is the engine for a series, and the release notes read that way: the medium sampler and the paper renderer are new Layer-1/Layer-2 primitives that every existing geom picks up for free. The second thread is correctness under real plot layouts — corner-aware label repulsion, boundary densification so bars bend under polar coordinates, reserved panel room so edge labels stop clipping. Geom coverage keeps widening in parallel, with chicklet charts the newest addition.
Expect the rest of the 2.x series to add media on top of the new sampler rather than more geoms, since that is where 2.0.0 put the extensibility. The default hachure-pitch change already shifts existing output slightly, so a follow-up patch tuning those defaults against real plots is likely.

Work is concentrated on making the package installable and check-clean rather than on the decomposition itself. The version stamps run out of order, with 2.0.3 predating both 2.0.2 and 2.0.4 by three years, so the feed reads as an archive flush around the CRAN return. Nothing in the entries points at method-level work.
Expect maintenance releases that keep the compiled code passing CRAN checks; the entries give no signal about new decomposition features.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
They serve adjacent needs but don't currently overlap on shipped themes. ggsketch and mmpca are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. ggsketch and mmpca are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
