⚠️There's a newer version (1.1.22) of this package.Take me there.

biganalytics (version 1.1.1)

A library of utilities for big.matrix objects of package bigmemory.

Description

This package extends the bigmemory package with various analytics. Functions bigkmeans and binit may also be used with native R objects. For tapply-like functions, the bigtabulate package may also be helpful. For linear algebra support, see bigalgebra. For mutex (locking) support for advanced shared-memory usage, see synchronicity.
