推荐答案

要从给定包中更改功能，您可能需要trace函数，它可以帮助您编辑和修改函数F

To change a function from a given package, you'll probably need trace function, it helps you edit and modify a function F

trace("F",edit=TRUE)

它将打开一个小窗口供您修改代码，但不会永久更改实际的源代码. 您可以复制并粘贴代码，并通过自己的修改创建新功能.

it will open a small window for you to modify the code, but it won't change the actual source code permanently. you can copy and paste the code and create a new function with your own modifications.
