ore.envAsEmptyenv
|
A logical value that specifies whether an environment referenced in an object should be replaced with an empty environment during serialization to an Oracle Database. When TRUE , the referenced environment in the object is replaced with an empty environment whose parent is .GlobalEnv , and the objects in the original referenced environment are not serialized. In some cases, this can significantly reduce the size of serialized objects. When FALSE , all of the objects in the referenced environment are serialized, and can be unserialized and loaded into memory. The default value for this option is FALSE .
The following Oracle R Enterprise functions use this global option:
-
ore.push , in saving a serialized list object to the database
-
ore.save , in saving objects to an Oracle R Enterprise datastore
-
ore.doEval and the other embedded R execution functions for serializing parameters of list type and for serializing some objects returned by an R function during embedded R execution

ore.na.extract
|
A logical value used during logical subscripting of an ore.frame or ore.vector object. When TRUE , rows or elements with an NA logical subscript produce rows or elements with NA values, which mimics how R treats missing value logical subscripting of data.frame and vector objects.
When FALSE , an NA logical subscript is interpreted as a FALSE value, resulting in the removal of the corresponding row or element. The default value is FALSE .
|
ore.parallel
|
A preferred degree of parallelism to use in embedded R execution. One of the following:
-
A positive integer greater than or equal to 2 for a specific degree of parallelism
-
FALSE or 1 for no parallelism
-
TRUE for the default parallelism of the data argument
-
NULL for the database default for the operation
The default value is NULL .
|
ore.sep
|
A character string that specifies the separator to use between multiple column row names of an ore.frame . The default value is | .
|
ore.trace
|
A logical value that specifies whether iterative Oracle R Enterprise functions should print output at each iteration. The default value is FALSE .
|
ore.warn.order
|
A logical value that specifies whether Oracle R Enterprise displays a warning message when an ore.frame that lacks row names or an ore.vector that lacks element names is used in a function that requires ordering. The default value is TRUE .
