update_blueprint: Update a preprocessing blueprint

In tidymodels/hardhat: Construct Modeling Packages

Update a preprocessing blueprint

Description

update_blueprint() is the correct way to alter elements of an existing blueprint object. It has two benefits over just doing blueprint$elem <- new_elem.

• The name you are updating must already exist in the blueprint. This prevents you from accidentally updating non-existent elements.

• The constructor for the blueprint is automatically run after the update by refresh_blueprint() to ensure that the blueprint is still valid.

Usage

update_blueprint(blueprint, ...)

Arguments

blueprint	A preprocessing blueprint.
...	Name-value pairs of existing elements in blueprint that should be updated.

Examples

blueprint <- default_xy_blueprint()

# `intercept` defaults to FALSE
blueprint

update_blueprint(blueprint, intercept = TRUE)

# Can't update non-existent elements
try(update_blueprint(blueprint, intercpt = TRUE))

# Can't add non-valid elements
try(update_blueprint(blueprint, intercept = 1))
