big.matrix-class: Class ``big.matrix''.
Description
The big.matrix class is designed for matrices with
elements consisting of the C types double, integer, short, or char.
A big.matrix acts much like a traditional R matrix, but helps protect
the user from many inadvertant memory-consuming pitfalls of traditional R
matrices and data frames. In Unix, they may also be used in shared memory.Objects from the Class
Objects can be created by calls of the form new("big.matrix", ...).
The functions big.matrix() and
shared.big.matrix() are intended for the user.
