Manage Massive Matrices with Shared Memory and Memory-Mapped
Files
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.
Fixed a bug with handling raw bytes. Now it is possible to
use big.matrix to store arbitrary R object (using serialization).
If you want to make sure that bigmemory big.matrix handles raw
data, add "bigmemory (>=4.5.21)" to the Depends stanza in
the Description.
bigmemory >= 2.2.0 is accompanied by sister packages
biganalytics and bigtabulate; mutexes (locking) are
abstracted to package synchronicity, available now
on R-Forge and soon to be uploaded to CRAN. Package
bigalgebra is on R-Forge as a beta version while we
sort through the range of library configuration options.
