Sorry for my confusing expression.
I need create some new temp functions after the package is loaded. And
these new functions should be visible and usable.
Functions could be returned as a object, as Liaw mentioned. However I
can't find some examples in R-intro. I also want to know whether
functions returned by their "father function" could be called outside.
Thank u all.
