Normally S3 methods such as as.ts.zoo are not exported unless there is
particular reason to access them directly.  Rather one accesses them
via their generic which dispatches the appropriate method based on the
class of its first argument.

That is if z is a zoo object then as.ts(z) dispatches as.ts.zoo.

If you really want to see it you can do this zoo:::as.ts.zoo
