# CxR Library
|
|
|
|
The `(scheme cxr)` library exports twenty-four procedures which are the compositions of from three to four `car` and `cdr` operations. For example `caddar` is defined by:
|
|
|
|
(define caddar
|
|
(lambda (x) (car (cdr (cdr (car x))))))
|
|
|
|
The procedures `car` and `cdr` themselves and the four two-level compositions are included in the base library.
|
|
|
|
For more information see the [R<sup>7</sup>RS Scheme Specification](../../r7rs.pdf).
