The option column controls options for the functions that are used to evaluate the workflow set, such as tune::fit_resamples() or tune::tune_grid(). Examples of common options to set for these functions include param_info and grid.

These functions are helpful for manipulating the information in the option column.

Usage

option_add(x, ..., id = NULL, strict = FALSE)

option_remove(x, ...)

option_add_parameters(x, id = NULL, strict = FALSE)

Arguments

x

A workflow set.

...

A list of named options to pass to the tune_*() functions (e.g. tune::tune_grid()) or tune::fit_resamples(). For option_remove() this can be a series of unquoted option names.

id

A character string of one or more values from the wflow_id column that indicates which options to update. By default, all workflows are updated.

strict

A logical; show execution stop if existing options are being replaced?

Value

An updated workflow set.

Details

option_add() is used to update all of the options in a workflow set.

option_remove() will eliminate specific options across rows.

option_add_parameters() adds a parameter object to the option column (if parameters are being tuned).

Note that executing a function on the workflow set, such as tune_grid(), will add any options given to that function to the option column.

These functions do not control options for the individual workflows, such as the recipe blueprint. When creating a workflow manually, use workflows::add_model() or workflows::add_recipe() to specify. extra options. To alter these in a workflow set, use update_workflow_model() or update_workflow_recipe().

Examples

  option_add(grid = 10)
