Improvements

  • Improved error message for misspelled argument in step functions. (#1318)

  • recipe() can now take data.frames with list-columns or sf data.frames as input to data. (#1283)

  • recipe() will now show better error when columns are misspelled in formula (#1283).

  • add_role() now errors if a column would simultaneously have roles "outcome" and "predictor". (#935)

  • prep() will now error if the ptype of the data doesn't match which was used to define the recipe. (#793)

  • Added more documentation in ?selections about how tidyselect::everything() works in recipes. (#1259)

  • New extract_fit_time() method has been added that returns the time it took to train the recipe. (#1071)

  • step_spline_b(), step_spline_convex(), step_spline_monotone(), and step_spline_nonnegative() now throws informative errors if thedegree, deg_free, and complete_set arguments causes an error. (#1170)

  • step_mutate() gained .pkgs argument to specify what packages need to be loaded for step to work. (#1282)

  • step_interact() now gives better error if terms isn't a formula. (#1299)

  • The prefix argument of step_dummy_multi_choice() is now properly documented. (#1298)

  • Significant speedup in step_dummy() when applied to many columns. (#1305)

  • step_dummy() now gives an informative error on attempt to generate too many columns to fit in memory. (#828)

  • step_dummy() and step_unknown() now throw more informative warnings for unseen levels. (#450)

  • step_dummy() now throws more informative warnings for NA values. (#450)

Bug Fixes

  • NA levels in factors aren't dropped when passed to recipe(). (#1291)

  • recipe() no longer crashes when given long formula expression (#1283).

  • Fixed bug in step_ns() and step_bs() where knots field in options argument wasn't correctly used. (#1297)

  • Bug fixed in step_interact() where long formulas were used. (#1231, #1289)

  • Fixed documentation mistake where default value of keep_original_cols argument were wrong. (#1314)

Developer

  • Developer helper function recipes_ptype() has been added, returning expected input data for prep() and bake() for a given recipe object. (#1329)

  • Developer helper function recipes_ptype_validate() has been added, to validate new data is compatible with recipe ptype. (#793)

  • Developer helper functions recipes_names_predictors() and recipes_names_outcomes() have been added to aid variable selection in steps. (#1026)
