atsign: Overloaded infix @ for attribute access

Description Usage Arguments Details Value See Also Examples

The at-sign, '@', is normally used with S4 objects for slot access. These functions allow the use of infix @ on non-S4 objects to get and set attributes.

object@name

object@name <- value

`object`	A non-S4 object.
`name`	The character-string name of the attribute to access, quoted or not.
`value`	The value of the attribute to be set.

The right-hand-side of the @ operator (the name argument) need not be quoted. It is converted to a literal character string by computation on the language using match.call. Attribute names must be matched exactly.

These functions check whether their left-hand argument is an S4 object, and if so, pass it through to the slot function, leaving the original use of @ for slot access unaffected.

The value of the attribute.
