Eclipse could be designed to list all classes which match a given name, when a valid class does not exist. For instance the only BigInteger class is java.math.BigInteger , perhaps if you had your own custom BigInteger extends MyClass , in another package in the build path, then Eclipse would only...

R: Create a Generic Version of a Function - ETH Z Create a Generic Version of a Function Description. Create a generic version of the named function so that methods may be defined for it. A call to setMethod will call setGeneric automatically if applied to a non-generic function.. An explicit call to setGeneric is usually not required, but doesn't hurt and makes explicit that methods are being defined for a non-generic function.

R: General Information on Methods Unlike ordinary functions, the generic has a slot that specifies its package. In an R session, there is one version of each such generic, regardless of where the call to that generic originated, and the generic function has a table of all the methods currently available for it; that is, all the methods in packages currently loaded into the session. R: Create and Save a Method - ETH Zurich The package name of a generic is set according to the package from which it originally comes; in particular, and frequently, the package where a non-generic version of the function originated. For example, generic functions for all the functions in package base will have "base" as the package name, although none of them is an S4 generic on that package.
