please see the code below. foo2 fails to dispatch correctly, but foo
does fine. i have tried 'cacheMetaData(1)' and a number of different
variants of 'cacheGenericsMetaData', on the possibility there is a
caching issue. but i still can't sort it out.
also one general question: does it really matter what's in the body
of the function definition in a 'setGroupGeneric' call? the actual
group function definition is always overwritten by a message to the
effect the function should not be called directly.
__
setGroupGeneric("Foo", function(x) standardGeneric("Foo"))
setGroupGeneric("Foo2", function(x, y) standardGeneric("Foo2"))
setGeneric("foo", function(x) standardGeneric("foo"),
group = "Foo", useAsDefault = function(x) "Default")
setGeneric("foo2", function(x, y) standardGeneric("foo2"),
group = "Foo2", useAsDefault = function(x, y) "Default2")
setMethod("Foo", signature(x = "numeric"), function(x) "Special")
setMethod("Foo2", signature(x = "numeric", y = "missing"),
function(x, y) "Special2")
foo(1) # gives the group method
foo2(1) # gives the default method
selectMethod("foo2", signature(x = "numeric", y = "missing")) # but
method selection appears to work correctly
