Number of unique values for pre-processing — min_unique • dials

Some pre-processing parameters require a minimum number of unique data points to proceed. Used in recipes::step_discretize().

Usage

min_unique(range = c(5L, 15L), trans = NULL)

Arguments

range: A two-element vector holding the defaults for the smallest and largest possible values, respectively. If a transformation is specified, these values should be in the transformed units.
trans: A trans object from the scales package, such as scales::transform_log10() or scales::transform_reciprocal(). If not provided, the default is used which matches the units used in range. If no transformation, NULL.

Examples

min_unique()
#> Unique Value Threshold (quantitative)
#> Range: [5, 15]
