Full Internal Workflow for Model and Recipe

Source: R/internals-full-make-wflw.R
full_internal_make_wflw.Rd

This function creates a full internal workflow for a model and recipe combination.

Usage

full_internal_make_wflw(.model_tbl, .rec_obj)

Arguments

.model_tbl

A model specification table (tidyaml_mod_spec_tbl).

.rec_obj

A recipe object.

Value

The function returns a workflow object for the first model-recipe pair based on the internal function selected.

Details

The function checks if the input model specification table inherits the class 'tidyaml_mod_spec_tbl'. It then manipulates the input table, making adjustments for factors and creating a list of grouped models. For each model-recipe pair, it uses the appropriate internal function based on the model type to create a workflow object. The specific internal function is selected using a switch statement based on the class of the model.
