bigmemory 4.2.3
...een extracted and will
be available through package synchronicity (on R-Forge, soon to appear
on CRAN). Initial versions of packages biganalytics and bigtabulate
are on CRAN, and new versions which resolve the warnings and have
streamlined CRAN-friendly configurations will appear shortly. Package
bigalgebra will remain on R-Forge for the time being as the
user-interface is developed and the configuration possibilities
expand.

This package extends the bigmemory package with various analytics.
Functions bigkmeans and binit may also be used with native R

be helpful. For linear algebra support, see bigalgebra. For mutex
(locking) support for advanced shared-memory usage, see
synchronicity.
