| signature-class {methods} | R Documentation | 
This class represents the mapping of some of the formal
arguments of a function onto the names of some classes.  It is used as
one of two slots in the MethodDefinition-class.
Objects can be created by calls of the form new("signature",
    functionDef, ...).  The functionDef argument, if it is
supplied as a function object, defines the formal names.  The other
arguments define the classes.
.Data:"character" the classes. names:"character" the
corresponding argument names. 
Class "character", from data part.
Class "vector", by class "character".
signature(object = "signature"): see the
discussion of objects from the class, above.
