TERR Data Functions

TERR is an implementation of the R programming language that provides restricted and unrestricted execution environments. TERR data functions running in unrestricted mode have access to the operating system and can run arbitrary commands.


Component	Description
Authorization	Members of the Script Author group can save data functions as trusted to be executed in unrestricted mode for other users. Spotfire Statistics Services can be configured to require authentication. It runs as a separate product. TERR service runs in a node manager and is called using the Spotfire Server acting as a reverse proxy. It requires an authenticated Spotfire session.
Execution context	A TERR data function runs locally or remotely. Local execution takes place on the Spotfire client itself. Remote execution is when a TERR data function is sent off from a Spotfire client, Spotfire Web Player service, or Spotfire Automation Services service to a TIBCO Spotfire Statistics Services service (a stand-alone product) or TERR service (which runs on a node manager).
