CRAN release: 2023-04-03
The constructor functions for single parameters,
new_qual_param(), as well as for parameter sets,
parameters_constr(), now have improved handling of the call shown in error messages (#291, #295).
CRAN release: 2022-11-04
defaultargument to the constructors
value_seq()now uses the same logic to generate a sequence of parameter values regardless of how long that sequence is (#153, #229).
The label for

Chicagodata set was removed. It can be found in the
CRAN release: 2022-01-31
summary_stat()is a new parameter for use in
class_weights()parameter was added for imbalanced models.
vocabulary_size()is a new parameter used in
CRAN release: 2021-09-10
conditional_test_typefor models with the
stop_iter()for early stopping.
Re-licensed package from GPL-2 to MIT. See consent from copyright holders here.
param_set(), scheduled for removal in version 0.0.5, is now removed.
CRAN release: 2020-09-16
A new function,
pull_dials_object()was also added.
Duplicate parameter combinations are now automatically removed from grid results.
The range for
epochs()was change to start at 10 iterations instead of 1.
The lower range for
spline_degree()now starts at 1 instead of 3.
The upper range for
cost()now goes to
CRAN release: 2020-07-08
- A number of new parameter objects associated with engine-specific functions were added for engines “ranger”, “randomForest”, “earth” and “C5.0”.
CRAN release: 2020-06-10
grid_*()functions no longer generate subclassed tibbles.
tune_grid()can now handle a named vector, to account for differences in ordering.
CRAN release: 2020-04-03
- Quick bug fix release related to range checks in 0.0.5. The check is more forgiving when the required type is integer and a double is provided.
CRAN release: 2020-04-01
When kept in the original units, a parameter’s range must now be the same data type as the parameter.
A bug in space filling designs with qualitative parameters was fixed (#94)
A better error message was created when grids are used with parameters sets that contain parameters that require finalization (#99)
Space-filling desings now share the same attributes as other grid objects (#100)
CRAN release: 2019-12-02
param_set()is being renamed
parameters(). The old name implied that you only use it to set parameters (say from a recipe or model rather than de novo).
param_set()will be available until version 0.0.5.
The range for
num_hash()was increase to be
The range for
max_tokens()was changed to be 0 to 1000.
CRAN release: 2019-10-01
All parameter objects are now parameter functions. For example, the pre-configured object
mtryis now a function,
mtry(), with arguments for the
trans. This provides greater flexibility in parameter creation, and should feel more natural.
deg_free()erroneously produced real values; integers are now returned.
update.param_set()now takes multiple named arguments.
CRAN release: 2018-12-09
Parameter objects now contain code to finalize their values and a number of helper functions for certain data-specific parameters. A
forceoption can be used to avoid updating the values.
Parameter objects are printed differently inside of tibbles.
regularizationwas changed to
penaltyin a few models to be consistent with this change.
Added a set of parameters for the
textrecipespackage issue 16.
