Oracle Machine Learning for R includes components on the Oracle AI Database server that enable an Oracle Machine Learning for R client to interact with Oracle Machine Learning for R Server.

The components are:

• Oracle Machine Learning for R Server

  • The RQSYS schema

  • Metadata and executable code in sys

  • Oracle Machine Learning for R Server libraries in $ORACLE_HOME/lib

  • Oracle Machine Learning for R R packages in $ORACLE_HOME/R/library

    The Oracle Machine Learning for R packages and supporting packages on the server support embedded R execution. These same packages must be installed separately on each client computer. (See About the Oracle Machine Learning for R Packages).

See the following topics for additional information:

• Table 1-3 for a list of supported R and OML4R versions.
• Figure 1-2 for an illustration of the server and client components of OML4R.
