Description

Automatically prep a data.frame/tibble for use in the k-NN algorithm.

Usage

hai_knn_data_prepper(.data, .recipe_formula)

Value

Arguments

.data

The data that you are passing to the function. Can be any type of data that is accepted by the data parameter of the recipes::reciep() function.
