Assign Label to an Object and Return It

Description

This function assigns a label to any kind of object. The label later can be retrieved and reused.

Usage

label(x)
label(x) <- value

Arguments

value	any expression.
x	any object.

Details

The label can be any expression assigned to any object. It is stored as a character attribute. Inheritance is not implemented, so by any transformation of the object into another one, the label is lost.

Print out the label value.
