\name{makeClassRepresentation}
\alias{makeClassRepresentation}
\title{ Create a Class Definition }
\description{
Constructs a \code{\link{classRepresentation-class}} object to
describe a particular class.  Mostly a utility function, but you can
call it to create a class definition without assigning it, as
\code{\link{setClass}} would do.
}
\usage{
makeClassRepresentation(name, slots=list(), superClasses=character(),
          prototype=NULL, package, validity, access, virtual=NA)
}
\arguments{
  \item{name}{ character string name for the class }
  \item{slots}{ named list of slot classes as would be supplied to
  \code{setClass}, but \emph{without} the unnamed arguments for superClasses if any. }
  \item{superClasses}{ what classes does this class extend }
  \item{prototype}{ an object providing the default
    data for the class, e.g, the result of a call to \code{\link{prototype}}. }
  \item{package}{ The character string name for the package in which
  the class will be stored; see \code{\link{getPackageName}}. }
  \item{validity}{Optional validity method.  See
      \code{\link{validObject}}, and the discussion of validity
      methods in the reference.}
   \item{access}{Access information.  Not currently used.
       }
  \item{virtual}{ Is this known to be a virtual class? }

  The R package \code{methods} implements, with a few exceptions, the
  programming interface for classes
  and methods in the book \emph{Programming with Data} (John
  M. Chambers, Springer, 1998), in particular sections 1.6, 2.7, 2.8,
  and chapters 7 and 8.

  While the programming interface for the methods package follows the reference,
  the R software is an original implementation, so details in
  the reference that reflect the S4 implementation may appear
  differently in R.  Also, there are extensions to the programming
  interface developed more recently than the reference.  For a
  discussion of details and ongoing development, see the web page 
  \url{http://developer.r-project.org/methodsPackage.html} and the
  pointers from that page.
