A user or an administrator can specify a variety of files and environment variables to customize a Spotfire Enterprise Runtime for R session. These files and environment variables are processed in the following order when the session starts.

1. TERRenviron files.
2. TERRprofile files.
3. .TERRData files.
4. .First function.

Changing them does not affect the current session of Spotfire Enterprise Runtime for R.

For a detailed description of using these files and environment variables to customize your Spotfire Enterprise Runtime for R session, see Customize the TERR environment at startup in the Spotfire Enterprise Runtime for R Technical Documentation.
