Thanks for reply.
as I said , the function in the package is like
myplot <- function(x,y) { plot(x,y) }
not like
myplot <- function(x,y) { plot(x,y,...) }
And I cant change the function inside the package!!
So , in this case how to solve the problem ?

That's where the three-dot argument is for.
See "Introduction to R", paragraph 10.4 The ‘…’ argument.
