\description{
These are utilities, currently in the methods package, that either
provide some functionality needed by the package (e.g., element
matching by name), or add compatibility with S-Plus, or both.

\describe{
  \item{\code{allNames}:}{ 
  the character vector of names (unlike names(), never returns NULL)
}
  
  \item{\code{getFunction}:}{ 
  find the object as a function.
}
  
  \item{\code{elNamed}:}{ 
  get the element of the vector corresponding to name.  Unlike the
  \code{[}, \code{[[}, and \code{$} operators, this function requires %]}}$
  \code{name} to match the element name exactly (no partial matching).
  }
  \item{\code{formalArgs}:}{ 
  Returns the names of the formal arguments of this function.
}
  
  \item{\code{existsFunction}:}{ 
  Is there a function of this name? If \code{generic==FALSE}, generic functions are not counted.
}
  
  \item{\code{findFunction}:}{ 
  return all the indices of the search list on which a function
definition for \code{name} exists.  

  If \code{generic} is \code{FALSE}, ignore generic
functions.
  }
  \item{\code{message}:}{ 
  output all the arguments, pasted together with no intervening spaces.
}
}
