It becomes a (S4) generic automagically when you define an S4 method
for it.  ;-)

{yes, I know this isn't the answer you wanted to hear;
 but really, maybe it's worth considering to use S4 classes and
 methods ?}

For S3, it's a bit uglier, but I think you could still do -- in your
package --

if(!exists("loadings.default", mode="function")) {
  loadings.default <- loadings
  loadings <- function(x, ...) UseMethod("loadings")
}

loadings.<myclass> <- function(x, ...) {
   ......... 
}

and S3-export these.
