Creates an S3 generic function
Note that this method is a internal method called by
setMethodS3() and there is no reason for calling it directly!
Creates a generic function in S3 style, i.e. setting a
function with name name that dispatches the method name
via UseMethod. If there is already a function named name
that function is renamed to name.default.
## Default S3 method:
setGenericS3(name, export=TRUE, envir=parent.frame(), dontWarn=getOption("dontWarnPkgs"),
validators=getOption("R.methodsS3:validators:setGenericS3"), overwrite=FALSE, ...)name |
The name of the generic function. |
export |
A |
envir |
The environment for where this method should be stored. |
dontWarn |
If a non-generic method with the same name is found it
will be "renamed" to a default method. If that method is found in
a package with a name that is not found in |
validators |
An optional |
... |
Not used. |
overwrite |
If |
