Update a preprocessing blueprint
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.
update_blueprint(blueprint, ...)
