Invoking R Scripts
The release of R currently available for use with Xpress Executor on the FICO Analytic Cloud is version 3.2.2 and includes all the base and recommended R packages. Additional packages can be installed by calling the standard R function "install.packages()"; these will be cached for the duration of the Mosel/scenario execution.
Some R functionalities are disabled, including:
- System calls and interaction with external native code
- Installation of additional packages that would require compilation
- All network access, except for the FICO CRAN mirror that is preconfigured as the default R package repository
