This is a preliminary list of procedures for the R7RS vector library. It is an upward compatible extension of the vector libraries of R5RS, R7RS-small, and SRFI 43, with additional procedures that are analogous to procedures in the SRFI 1 list 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.
make-vector (R5RS), vector (R5RS), vector-iota (SRFI 1) \\ vector-unfold (SRFI 43), vector-unfold-right (SRFI 43) \\ vector-copy (R7RS), vector-copy! (R7RS) \\ vector-reverse-copy (SRFI 43+), vector-reverse-copy! (SRFI 43+) \\ vector-append (R7RS), vector-append! (SRFI 1) \\ vector-append-subvectors (see below) \\ vector-concatenate (SRFI 43), vector-concatenate! (SRFI 1) \\ vector-tabulate (SRFI 1), vector-tabulate! (SRFI 1)
vector? (R5RS), vector-empty? (SRFI 43), vector= (SRFI 43+)
vector-ref (R5RS), vector-length (R5RS) \\ vector-take (SRFI 1), vector-take-right (SRFI 1) \\ vector-drop (SRFI 1), vector-drop-right (SRFI 1) \\ vector-split-at (SRFI 1)

The above procedures do not pass the index value to the mapping function, for compatibility with R7RS vector-map and vector-fold. The following versions, which are compatible with SRFI 43, pass the index value as the first argument.

(vector-append-subvectors k fill ( at vector start end stride ) ...)
Returns a newly allocated vector of length k after copying every stride-th element of each vector from start to end into the new vector starting at at. Any additional locations in the new vector are initialized with fill. This procedure is a generalization of vector-copy and 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.
(vector-cumulate proc seed vector)
Returns a newly allocated vector of the same length as vector. Each element is constructed by reducing (as if by vector-reduce) successive prefixes of the elements of vector. (APL scan.)
