R package healthyR.ts by spsanderson — release notes from GitHub.

github.com/spsanderson/healthyR.ts ↗

healthyR.ts keeps adding time-series helpers, then quietly breaks the old ones to modernise them.

time serieshealthyversestationarityggplot2breaking changesr package
◆Current state
A time-series companion in the healthyverse family, shipping helper functions in batches: growth-rate vectors, an ADF test and auto_stationarize() in 0.2.11, then five log and differencing transforms in 0.3.0, and a random-walk plot in 0.3.2. Alongside the additions runs a steady stream of breaking cleanups — invisible returns dropped, R 4.1 required for the native pipe, and ts_ma_plot() refactored onto ggplot2 facets with its xts output removed and its return value cut from six items to two.
◆Where it's heading
Two threads, both consistent. The functional one is coverage of the stationarity workflow — transform, test, auto-stationarize, plot — assembled function by function rather than as a single API. The structural one is convergence on ggplot2 and tidy conventions, retiring xts objects and multi-object return lists as it goes. The package is not afraid to break return shapes to get there, so upgrades are not drop-in.
◆Prediction
Expect the remaining functions that still return xts objects or bundled lists to get the same ggplot2-only treatment, since ts_ma_plot() was refactored on exactly that rationale.

◆Recent moves

  1. 6mo ago

    Random walk plot added; ts_ma_plot drops xts for ggplot2 facets

    Adds ts_random_walk_plot() for side-by-side random-variable and cumulative-path facets, and refactors ts_ma_plot() onto ggplot2::facet_wrap(), dropping its xts plotting and cutting the return from six objects to two. R 4.1 is now required. The ggplot2 consolidation continues at the cost of a breaking return shape.

    Invisible returns dropped; random walk and vva plot fixes

    Drops invisible returns as a breaking change, fixes ts_random_walk() generating three runs below a run count of two, and corrects ts_vva_plot() cumulative sums and lagged differences. A timetk holiday-signature step is removed after unexplained recycling errors.

    Five log and differencing transform utilities added

    Adds five transform utilities — log, single and double differencing, and their log variants — plus attributes on ts_growth_rate_vec() output and a parsnip auto_arima engine path when tuning is off. Fills in the manual half of the stationarity workflow that auto_stationarize() automates.

    Stationarity testing and auto_stationarize added

    Adds ts_growth_rate_vec(), ts_adf_test(), ts_growth_rate_augment() and auto_stationarize(). The release where stationarity testing and correction became first-class rather than something the user assembled.

    Single example fix

    A single upstream example fix contributed against rsample. No functional change.

    Boilerplate fitting uses show_best directly

    Changes the boilerplate fitting functions to take the single best tuning result rather than sorting everything and slicing. Internal tidying.
