TERR, the TERR Service, and Spotfire Statistics Services

Users of the Spotfire application for Windows can register and run TERR data functions by using the local TERR engine, or by using the TERR service. Web client users can use the defined TERR data functions in analyses in a web browser.

The engine that the data function authors specify depends on the statistics language used, and whether the analysis is going to be shared with others through the web client.

Note: Make sure you use the same release of TERR for analyses across services.

TERR

In the Spotfire application for Windows, you can create analyses that use TERR data functions or TERR custom expressions to run locally (on Windows only). The analyses can also use the built-in predictive analytics, which use the TERR engine that is provided with the Spotfire application for Windows. However, note that authors must have the correct Spotfire license to use the TERR engine.

To specify the local TERR engine:

In the installed Spotfire client, from the menu, click Tools > Options.
In the Options dialog, from the left list, select Data functions.

By default, the option Use locally-installed Spotfire Enterprise Runtime for R engine is selected.

TERR Service

The TERR service is installed on a node for your Spotfire Server. The TERR service is a licensed component of Spotfire Statistics Services. It is provided to Spotfire Enterprise customers on the Spotfire Download site. The TERR service provides functionality for deploying TERR data functions, expression functions, or other advanced analytics to web clients.

You can share analyses created using TERR data functions, TERR predictive analytics, or TERR custom expressions with users of the Spotfire web client. By default, when such an analysis is shared, the TERR service provides the functionality for the users.

Note: Data functions written to use open-source R require the Spotfire Service for R. They do not work with the TERR service.
