This is a preliminary list of procedures for the R7RS vector library.  It is an upward compatible extension of the vector libraries of [http://www.schemers.org/Documents/Standards/R5RS/ R5RS], [http://trac.sacrideo.us/wg/raw-attachment/wiki/WikiStart/r7rs.pdf R7RS-small], and [http://srfi.schemers.org/srfi-43/srfi-43.html SRFI 43], with additional procedures that are analogous to procedures in the [http://srfi.schemers.org/srfi-1/srfi-1.html SRFI 1] list library and the [http://srfi.schemers.org/srfi-13/srfi-13.html SRFI 13] string library.  As a single exception, the `vector-copy` procedure in R7RS-small does not provide the ''fill'' argument present in SRFI 43.

The procedures that are already in R7RS-small will not be overridden by this library, and are listed only for completeness.

Numeric vector analogues of these procedures, excluding the ones in NumericVectorsCowan, will be provided in a separate library.

== Notation ==

* R5RS means the procedure is available in R5RS and R7RS-small

* R5RS+ means the procedure is available in R5RS and with additional functionality in R7RS-small and SRFI 43.

* R7RS means the procedure is available in R7RS-small and SRFI 43.

* SRFI 43 means the procedure is available in SRFI 43.

* SRFI 43+ means either the procedure is available in SRFI 43 but additional functionality is proposed, or an analogous procedure is available in SRFI 43.

* SRFI 13 means an analogous procedure is available in SRFI 13.

* SRFI 1 means an analogous procedure is available in SRFI 1.

* SRFI 1/13 means an analogous procedure is available in both SRFI 1 and SRFI 13.

== Additional procedures ==

`(vector-append-subvectors `''k fill'' ( ''at vector start end'' ) ...`)`

Returns a newly allocated vector of length ''k'' after copying the portion of each ''vector'' from ''start'' to ''end'' into the new vector starting at ''at''.  Any additional locations are initialized with ''fill''.  This procedure is a generalization of `vector-copy!`.  Implementations may optimize this procedure using an unsafe primitive that creates an uninitialized vector, in order to avoid touching each element of the result twice.
