What is fdacluster?

Functional data clustering grew from one algorithm into a comparable suite

fdacluster clusters functional data while separating amplitude from phase variation, aligning curves as part of the clustering rather than before it. The algorithm set covers k-means, hierarchical clustering and DBSCAN, all producing a common caps result object so runs can be compared directly. Version 0.4.0 tightened the interface with is_domain_interval and transformation arguments describing the input data, added compatibility checking between incompatible option combinations, and split the L2 and normalized L2 distances into separate C++ classes to enforce that plain L2 cannot be combined with dilation or affine warping it is not invariant to.

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.

Functional data clustering grew from one algorithm into a comparable suite

◆ Current state

fdacluster clusters functional data while separating amplitude from phase variation, aligning curves as part of the clustering rather than before it. The algorithm set covers k-means, hierarchical clustering and DBSCAN, all producing a common caps result object so runs can be compared directly. Version 0.4.0 tightened the interface with is_domain_interval and transformation arguments describing the input data, added compatibility checking between incompatible option combinations, and split the L2 and normalized L2 distances into separate C++ classes to enforce that plain L2 cannot be combined with dilation or affine warping it is not invariant to.

◆ Where it's heading

The trajectory runs from method implementation toward guardrails and portability. Early releases added capability; recent ones prevent misuse and reduce weight - dplyr, forcats, tidyr and purrr removed in 0.4.0, furrr swapped for future.apply - while 0.4.2 is entirely C++ correctness, replacing Armadillo's whole-object finiteness check with scalar std::isfinite and fixing an integer overflow in linear index computation that broke large datasets. Cadence is roughly one release a year.

◆ Prediction

Given that the last two releases were dependency reduction and numerical correctness rather than method work, expect the next to continue in that vein unless a new clustering algorithm is contributed.

◆ Current state

◆ 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.
