ggsketch vs stochvol
A side-by-side editorial comparison of ggsketch and stochvol — release velocity, themes, recent moves, and the top alternatives to consider.
ggsketch vs stochvol: at a glance
What is ggsketch?
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.
What is stochvol?
A Bayesian volatility sampler in its maintenance decade, paying for its own speed
stochvol runs MCMC for stochastic volatility models, with a C++ sampler underneath an R interface. Five years of releases in this window contain no new models: the work is compiler and dependency compatibility, CRAN check notes, and a steady trickle of corrections to the sampler itself. Its methodological milestone, the Journal of Statistical Software paper, is recorded in a 2021 tag.

◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.

◆ Current state
stochvol runs MCMC for stochastic volatility models, with a C++ sampler underneath an R interface. Five years of releases in this window contain no new models: the work is compiler and dependency compatibility, CRAN check notes, and a steady trickle of corrections to the sampler itself. Its methodological milestone, the Journal of Statistical Software paper, is recorded in a 2021 tag.
◆ Where it's heading
This is what a finished computational package looks like. The formula interface arrived at 3.1.0 and nothing has been added since; what changes is the ground underneath — RcppArmadillo major versions, UBSan checks, error-handling conventions moving from Rf_error to Rcpp::stop for correct memory management. The recurring pattern worth watching is that several releases fix real errors in the sampler's proposal distributions, found by users and by CRAN's own instrumented checks rather than by the maintainer.
◆ Prediction
Nothing in these notes suggests new methodology. Expect the next release when RcppArmadillo or a CRAN check flavour forces one, and treat any bug report against the samplers as the more consequential event.
