10.3.1.3 Structure of Return Value

Another argument that applies to all of the Embedded R Execution functions is FUN.VALUE.

If the FUN.VALUE argument is NULL, then the ore.doEval and ore.tableApply function can return a serialized R object as an ore.object class object, and the ore.groupApply, ore.indexApply, and ore.rowApply functions return an ore.list object. However, if you specify a data.frame or an ore.frame with the FUN.VALUE argument, then the function returns an ore.frame that has the structure of the specified data.frame or ore.frame object.

To specify that the corresponding output column of an ore.frame have a CLOB or BLOB database data type, you can apply the attribute ora.type to a column of a FUN.VALUE data.frame.
