The ExecR system table operator is used to execute R scripts. Run the optional Database Initialization Program (DIP) script DipRTblOp to create the ExecR table operator. The DipRTblOp DIP script is not run as part of the DIPALL script. You must run it separately.

ExecR resides in the td_sysgpl database.

For information about DIP, see Teradata Vantage™ - Database Utilities , B035-1102 .
