 \section{Details}{
   \describe{
-    \item{\code{setGeneric}:}{
-      If there is already a non-generic function of this name, it will
-      be used to define the generic unless \code{def} is supplied, and
-      the current function will become the default method for the
-      generic.
-      If \code{def} is supplied, this defines the generic function, and
-      no default method will exist (often a good feature, if the
-      function should only be available for a meaningful subset of all
-      objects).
-      Arguments \code{group} and \code{valueClass} are retained for
-      consistency with S-Plus, but are currently not used.
-    }
     \item{\code{isGeneric}:}{
       If the \code{fdef} argument is supplied, take this as the
       definition of the generic, and test whether it is really a
       generic, with \code{f} as the name of the generic.  (This argument
       is not available in S-Plus.)
       re-establish the same generic function as before.
