Implements <code><a href="/link/which?package=bigmemory&version=4.6.4" data-mini-rdoc="bigmemory::which">which</a></code>-like functionality for a
<code>big.matrix</code>, with additional options for efficient comparisons
(executed in <acronym>C++</acronym>); also works for regular numeric matrices without
the memory overhead.

methods

Create, store, access, and manipulate massive matrices.
Matrices are allocated to shared memory and may use memory-mapped
files.  Packages 'biganalytics', 'bigtabulate', 'synchronicity', and
'bigalgebra' provide advanced functionality.
