[R] help needed: taking a function out of a package and it can not find some funtions

[Jason Liao]

 I tried to modify the R function bw.SJ (from the stats package) for my own use. But if I just get the source code and run directly (without any modification), it can no longer find some key functions called within it. I understand this has something to do with searching path which I do not understand well. Can anyone tell me how to modify the source code of an R function and still make it part of an existing package?

Thanks.
