参数

x

recipe 对象、步骤或检查(经过训练或以其他方式)。

...

目前未使用。

type

对于 step_pca ，可以是 "coef" (对于每个组件的变量加载)或 "variance" (每个组件占多少方差)。

number

整数或 NA 。如果缺少且未提供id，则返回值是配方中的操作列表。如果给出了一个数字，则为配方中的该操作执行 tidy 方法(如果存在)。如果提供id，则不得提供number。

id

字符串或 NA 。如果缺少且未提供number，则返回值是配方中的操作列表。如果给出了字符串，则为配方中的该操作执行 tidy 方法(如果存在)。如果提供number，则不得提供id。

值

一个小标题，其中的列根据执行的 tidy 方法而变化。当 number 和 id 为 NA 时，包含列 number(操作迭代)、operation("step" 或 "check")、type(方法，例如 "nzv"、"center")、一个名为 trained 的逻辑列(用于确定操作是否已使用 prep 进行估计)、一个逻辑列 skip 以及一个字符列 id 。
