test for existance of a method for given class
Dear All,
I want to test whether a method exists for given object. For example,
whether a function "deviance" is defined for an object of the "lm" class.
My imperfect understanding leads me to think something like
hasMethod("deviance", object)
hasMethod("deviance", "lm")
existsMethod("deviance", signature(class="lm"))
or similar might work (I don't fully understand how to manipulate
signatures), but all the variations on this I have tried return FALSE.
(Exce...

Utilities for methods
...r
utilities that should be faster and more convenient, at least when more
than one argument is involved.
The new utilities will be: findMethods(), which returns a simple list
of methods (replacement for getMethods()); findMethodSignatures(), which
returns a character matrix of signatures; and hasMethods(), which tests
for the existence of methods.
Cheers,
John
