R help - Mar 2003 - getMethod in a setMethod context

Dear List,

I am currently trying to use methods from other classes to avoid
code duplication (my settings are bit complicated, inheritance
is not completely giving what I want). What I would like
to do is to be able to "get the function in the method" to
use it elsewhere...

I tried the following, but apparently it does not work, any pointer ?

  setMethod("f", signature("B"),
            getMethod("f", signature="A"),
            where=where)



Thanks,


Laurent

Hi Laurent,

what about something like

   setMethod("f", signature("B"),
             definition=function(obj){
	        f(as(obj, "A")
              },
             where=where)
 


Cheers 

Michael

May not be what you want if the method for "A" calls generics for
which the class of the original obj would be more relevant.
