Prep Data for SVM_Poly - Recipe

Automatically prep a data.frame/tibble for use in the SVM_Poly algorithm.

Usage

hai_svm_poly_data_prepper(.data, .recipe_formula)

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.

.recipe_formula

The formula that is going to be passed. For example if you are using the diamonds data then the formula would most likely be something like price ~ .

Value

A recipe object

Details

This function will automatically prep your data.frame/tibble for use in the SVM_Poly algorithm. The SVM_Poly algorithm is for regression only.

This function will output a recipe specification.
