package: Distributed Data-structures in R

Description Commands Author(s) References Examples

Description

ddR simplifies large-scale data analysis. It includes new language constructs to express distributed programs in R. Distributed programs writted in ddR can work across multiple execution engines such as parallel, distributedR, and others. ddR provides data-structures such as distributed array darray to partition and share data across multiple R instances. Users can express parallel execution using dmapply.
