mlr3fda 0.7.0

CRAN release: 2026-07-02

  • fix: PipeOpFDAWavelets no longer errors when filter is a wt.filter object or a numeric vector. Generated columns are now named <column>_wav_<i> regardless of the filter.
  • fix: PipeOpFDAZoom now accepts a one-sided begin or end instead of requiring both.
  • fix: as.data.table(mlr_pipeops) no longer errors with object 'value' not found when mlr3fda is loaded.
  • feat: New PipeOpFDACatch22 for extracting the catch22 time series features from functional columns via Rcatch22::catch22_all().
  • feat: New PipeOpFDAIntegrate for extracting the definite integral of functional columns via tf::tf_integrate().

mlr3fda 0.6.0

CRAN release: 2026-06-01

  • fix: Add mlr3fda to mlr_reflections$loaded_packages to fix errors when using mlr3fda in parallel.
  • feat: New PipeOpFDADepth for computing the data depth of functional columns via tf::tf_depth().
  • feat: New PipeOpFDADerive for computing derivatives of functional columns via tf::tf_derive().
  • feat: PipeOpFDAExtract gained the "sd" feature for extracting the standard deviation.
  • perf: PipeOpFDAFourier is now several times faster.

mlr3fda 0.5.0

CRAN release: 2026-05-03

  • feat: New PipeOpFDARegister for aligning functional columns to a learned template via tf::tf_register().

  • fix: The fuel task now correctly names the scalar column h2o instead of h20.
  • feat: Mlr3Error and Mlr3Warning classes for errors and warnings.
  • feat: New PipeOpFDAFourier for extracting fast Fourier transform features from functional columns.

mlr3fda 0.3.0
