R is listed as one of the languages with built-in support in this 
wiki link.  I searched for  multiple dispatch because I was 
familiar with the similar feature in julia, and that's how they 
refer to it.
https://en.wikipedia.org/wiki/Multiple_dispatch

An excerpt statement from this wiki page is :
"  dynamically dispatched based on the run-time (dynamic) type 
or, in the more general case some other attribute, of more than 
one of its arguments"


Based on the 'some other attribute', I wonder if the library 
could conceivably be extended to dispatch based on the User 
Defined Attribute info

https://dlang.org/spec/attribute.html

@('c') string s;
pragma(msg, __traits(getAttributes, s)); // prints tuple('c')
