Extract A Model Fitted Workflow

Extract a model fitted workflow from a tidyAML model tibble.

Usage

extract_wflw_fit(.data, .model_id = NULL)

Arguments

.data

The model table that must have the class tidyaml_mod_spec_tbl.

.model_id

The model number that you want to select, Must be an integer or sequence of integers, ie. 1 or c(1,3,5) or 1:2

Value

A tibble with the chosen model workflow(s).

Details

This function allows you to get a model fitted workflow or more from a tibble with a class of "tidyaml_mod_spec_tbl". It allows you to select the model by the .model_id column. You can call the model id's by an integer or a sequence of integers.
