R: Create a Class Definition

makeClassRepresentation {methods} | R Documentation

## Create a Class Definition

### Description

Constructs an object of class `classRepresentation` to describe a particular class. Mostly a utility function, but you can call it to create a class definition without assigning it, as `setClass` would do.

### Usage

    makeClassRepresentation(name, slots=list(), superClasses=character(),
                            prototype=NULL, package, validity, access,
                            version, sealed, virtual=NA, where)

### Arguments

`name` | character string name for the class
`slots` | named list of slot classes as would be supplied to `setClass`, but without the unnamed arguments for superClasses if any.
`superClasses` | what classes does this class extend
`prototype` | an object providing the default data for the class, e.g, the result of a call to `prototype`.
`package` | The character string name for the package in which the class will be stored; see `getPackageName`.
`validity` | Optional validity method. See `validObject`, and the discussion of validity methods in the reference.
`access` | Access information. Not currently used.
`version` | Optional version key for version control. Currently generated, but not used.
`sealed` | Is the class sealed? See `setClass`.
`virtual` | Is this known to be a virtual class?
`where` | The environment from which to look for class definitions needed (e.g., for slots or superclasses). See the discussion of this argument under GenericFunctions.
