Near-zero variance parameters — freq_cut • dials

These parameters control the specificity of the filter for near-zero variance parameters in recipes::step_nzv().

Usage

freq_cut(range = c(5, 25), trans = NULL)

unique_cut(range = c(0, 100), 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.

Details

Smaller values of freq_cut() and unique_cut() make the filter less sensitive.

Examples

freq_cut()
#> Frequency Distribution Ratio (quantitative)
#> Range: [5, 25]
unique_cut()
#> % Unique Values (quantitative)
#> Range: [0, 100]
