What is ggdist?

The grammar of uncertainty visualization, now drawing the uncertainty in its own estimates.

ggdist supplies ggplot2 with a compositional vocabulary for distributions — slabs, intervals, dotplots and the sub-geometries that combine them. The last three years moved it from a drawing library to an estimation library: bounded density estimation with Sheather-Jones bandwidth became the default, weights propagate through every density, interval and point summary, and blurred dotplots render Monte Carlo standard error as visual fuzz. The 2025 release rounds this out with per-geometry thickness subscales and settable global defaults.

What is PESTO?

A calibration toolkit that found its core PEST++ bridge had never actually run

PESTO wraps PEST++ inversion for APSIM crop models from R. Version 0.10.0 rebuilt the PEST++ invocation layer after the maintainer found the shell-out had never executed: control variables were passed as /h :name=value, a syntax PEST++ has never accepted. Fifteen defects were present since the initial April 2026 release and shipped in every version after it. 0.10.1 followed with APSIM binary discovery via APSIM_EXE_PATH and a benchmark battery against real PEST 18, pestpp-ies 5.2.16 and native APSIM that reproduced the prior baseline at 0.0% deviation on every accuracy metric.

The grammar of uncertainty visualization, now drawing the uncertainty in its own estimates.

◆ Current state

ggdist supplies ggplot2 with a compositional vocabulary for distributions — slabs, intervals, dotplots and the sub-geometries that combine them. The last three years moved it from a drawing library to an estimation library: bounded density estimation with Sheather-Jones bandwidth became the default, weights propagate through every density, interval and point summary, and blurred dotplots render Monte Carlo standard error as visual fuzz. The 2025 release rounds this out with per-geometry thickness subscales and settable global defaults.

◆ Where it's heading

Two threads run in parallel and keep converging. One is statistical: pluggable density estimators arrived first, then became the default, then gained weights and quantile histograms. The other is compositional: sub-geometries acquired their own guides, then their own scales, so a slab's thickness axis is now a first-class annotated dimension. Cadence has stretched from twice-yearly to roughly annual, with the recent work tightening existing surface rather than opening new.

◆ Prediction

Subguides gained subscales a release later, so the remaining asymmetry is in the sub-geometry system rather than the statistics; expect the next release to continue that fill-in work.

◆ Current state

Version 0.10.0 rebuilt the PEST++ invocation layer after the maintainer found the shell-out had never executed: control variables were passed as /h :name=value, a syntax PEST++ has never accepted.

◆ Where it's heading

The arc runs from packaging discipline toward working software, and the ordering is unusual. Releases 0.4.0 and 0.4.1 were governance and metadata passes: citation files, code of conduct, canonical URL migration to AAGI. 0.7.0 broadened the forward-model templates to ODE, crop-growth and SEIR forms and promoted the observation schema to public API. Only at 0.10.0 did the project ground itself against the actual USGS sources and a real pestpp binary, which is precisely when the defects surfaced.

◆ Prediction

Expect the next releases to widen the real-engine test matrix - more PEST++ variants and pinned APSIM versions exercised in CI - rather than add new forward-model families, since verification is now the stated priority in every release note.
