The Spotfire Service for R provides Spotfire clients with the ability to execute open-source R code, using the user-installed R engine, on the R service node.

Spotfire Service for R is required to execute data functions in Spotfire files from Spotfire Automation Services and Spotfire Web Player, because those services do not have R engines.

The Spotfire Service for R itself is running the service as the same user account as is running the node manager on which the service runs. See Node Manager.

By default, R scripts executed by the Spotfire Service for R on behalf of its users are executed in a different execution context, as explained here.
