Rshare: Rshare: the shared environment package
In Rshare: Shared environment across multiple independent R sessions

Description Implementation Details Author(s)

This is the Rshare package. It is used to create a shared environment available to multiple R sessions. The environment is hosted and served by one R session, and other R sessions may subscribe to this environment as clients. Environments are parameterized by a port number. Objects may be written to and read from the shared environment. For an overview of the functions used to access the shared environment, see See get.Rshare

Server-side Hooks

In addition, a simple method of registering server-side hooks allows users to create custom functionality. These hooks work by dispatching certain types of objects received by the server to user-defined functions. User-defined functions may do anything, from displaying a message in the console to running an analysis and returning customized data. See registerRshareHook for more information.

The package works by utilizing Tcl sockets to create a lightweight framework for different R sessions to share data. It is written with a mixture of R and Tcl code to allow for portability across mutliple operating systems. Be warned, the package is far from complete and functionality may change in the future to address current limitations.
