R Gateway Support

To connect InterSystems IRIS to an R interpreter, you use the R Gateway with Rserve, a TCP/IP server for R, and the R-Engine Java client. This integration enables direct R-based statistical computations and analysis within your IRIS applications.

Before using the R Gateway, you need to install Java 8+, InterSystems IRIS 2020.4 or later, an R interpreter, and Rserve. These components establish the TCP/IP connection required to execute R commands from your IRIS environment.

You can build predictive models and analyze complex datasets in R, then integrate the results within InterSystems IRIS applications. This connection facilitates using R computations directly for reporting or further data processing inside your IRIS environment.

The R Gateway mechanism works by utilizing Rserve as a TCP/IP server for the R interpreter and R-Engine as a Java client. This architecture allows InterSystems IRIS applications to send commands to Rserve and retrieve statistical computation results.

Yes, InterSystems IRIS requires Java 8 or higher to support R integration. The R Gateway relies on a Java client called R-Engine to communicate with the Rserve server and execute statistical computations within your IRIS applications.

Using Rserve provides a dedicated TCP/IP server interface for the R interpreter, allowing the Java-based R-Engine client within InterSystems IRIS to communicate efficiently. This architecture supports stable statistical analysis and R-based computations without direct execution overhead.
