SharedObject: Sharing R objects across multiple R processes without memory duplication
This package is developed for facilitating parallel computing in R. It is capable to create an R object in the shared memory space and share the data across multiple R processes. It avoids the overhead of memory duplication and data transfer, which make sharing big data objects across many clusters possible.
