How to access functions called from StandardGeneric?

Question

I am trying to correct a small error in a R package. My problem is that the function I would like to modify is called through standardGeneric instance. I tried to trace the function :

trace('regFit', edit=TRUE)

But it does not display the actual function content. Would you know how I can access it?

Answer 1

如果运行debug(regFit) ，则使用n一步进入该函数，它应进入第二步或第三步使用的方法。
