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"))
