TERRenviron

The optional TERRenviron files can contain the definitions of environment variables to specify such customizations as JAVA_HOME and the project directory for TIBCO Enterprise Runtime for R. TERRenviron is the first file run in a customized TIBCO Enterprise Runtime for R startup.

TERRenviron files can be defined in two places:

The site-specific file in TERR.home (for example, in etc/TERRenviron)
The user-specific file in ./.TERRenviron (or in ~/.TERRenviron if ./.TERRenviron does not exist).

You can define environment variables for the TIBCO Enterprise Runtime for R session using bash-like syntax in the TERRenviron files. Typical lines are as follows.

VAR_NAME="variable's value"
ETC_PATH=${TERR_HOME}/etc
VAR_WITH_DEFAULT=${VAR_WITH_DEFAULT-"var's default value"}

The syntax ${VAR_NAME} specifies that ${VAR_NAME} should be replaced with the value of the environment variable VAR_NAME. If the environment variable is not defined, it should be replaced with an empty string.
The syntax ${VAR_WITH_DEFAULT-"var's default value"} specifies that ${VAR_NAME-"var's default value"} should be replaced with the value of the environment variable VAR_NAME if VAR_NAME is defined. Otherwise, it should be replaced with "var's default value".

If you want to start a session and bypass running the TERRenviron files, you can use one of the following techniques.

Use the command line option --no-environ.
Use the command-line option --vanilla.

You can use nonstandard-named TERRenviron files by defining the environment variables TERR_ENVIRON and TERR_ENVIRON_USER, setting the name to the site-specific and user-specific environment files, respectively.

Note: TIBCO Enterprise Runtime for R does not report warnings or errors if these files do not exist.

Example

JAVA_HOME="C:/Program Files/Java/jre8"
