# The Spotfire® Enterprise Runtime for R - Server Edition

The Spotfire® Enterprise Runtime for R - Server Edition (a/k/a TERR service) extends access to the Spotfire Enterprise Runtime for R (a/k/a TERR™) engine from the installed Spotfire client to Spotfire web client users.

The TERR™ - Server Edition (a/k/a TERR™ service) is provided to Spotfire® Server administrators as a set of Spotfire SPK packages, in one SDN distribution file. Spotfire Server administrators can install and configure the TERR service on a node manager that is available to the Spotfire Server.

The ability to develop predictive analytics, data functions, or TERR™ expressions is available only to authors using the installed Spotfire client, but users of the web client can take advantage of the added functionality.

This document is meant for Spotfire Server administrators who need to install and configure the TERR service, to install R packages for data functions and analyses that use them, and to review logs and troubleshoot the TERR service.
