⚠️There's a newer version (0.5-1) of this package.Take me there.

pbdDMAT (version 0.2-3)

Programming with Big Data -- Distributed Matrix Methods

Description

pbdDMAT contains high level S3 and S4 methods for creating, modifying, and performing computations with dense, distributed matrices. This includes a new class, 'ddmatrix', for storing all of the distributed data details. Computation is handled mostly by routines from the pbdBASE package.
