freq_cut: Near-zero variance parameters

In dials: Tools for Creating Tuning Parameter Values

Near-zero variance parameters

Description

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()
unique_cut()
