Release Notes
Release 1.5.1
E83205-02
April 2017
These release notes contain important information about Release 1.5.1 of Oracle R Enterprise.
Oracle R Enterprise 1.5.1 has some new features that are compatible with Oracle Database Release 12.1.0.2 and earlier, and other new features compatible with Oracle Database Release 12.2.0.1.
OREdplyr package, improved performance of row ordering in ore.frame objects, and faster loading of the Oracle R Enterprise packages.OAAgraph and has new functions in the Oracle R Enterprise Data Mining package OREdm.Parent topic: Oracle R Enterprise 1.5.1 Release Notes
Oracle R Enterprise 1.5.1 has the new OREdplyr package, improved performance of row ordering in ore.frame objects, and faster loading of the Oracle R Enterprise packages.
OREdplyr Package for Data Manipulation
The dplyr package provides a grammar of data manipulation functions for data.frame objects and numeric objects. The new OREdplyr package implements much of this functionality for ore.frame and ore.numeric objects. This enables in-database execution of dplyr functionality such as selecting, filtering, ordering, and grouping columns and rows, and joining, summarizing, sampling, and ranking rows.

The OAAgraph package provides an R interface to the powerful Oracle Spatial and Graph Property Graph In-Memory Analyst (PGX) for use in combination with Oracle R Enterprise and database tables.
The package provides a single, unified interface supporting the complementary use of machine learning and graph analytics technologies.
Graph analytics use graph representations of data, in which data entities are nodes and relationships are edges. Machine learning produces models that identify patterns in data for both descriptive and predictive analytics. Together, these technologies complement and augment one another.

The OREdm package has some new functions that use in-database Oracle Data Mining algorithms to create models in the database and new arguments for some functions.
New Functions in the OREdm Package
New functions in the OREdm Oracle Data Mining package that use in-database algorithms are the following:
ore.odmEM, Expectation Maximization Models
ore.odmESA, Explicit Semantic Analysis Models
ore.odmRAlg, Extensible R Algorithm Models
ore.odmSVD, Singular Value Decomposition Models
The ore.odmRAlg enables users to use registered R scripts to create models that use the Oracle Data Mining in-database model framework.
Other new functions are the following:
partitions, which returns partition names from a partitioned model
settings, which returns the Oracle Data Mining parameter settings used to build the model.
New Arguments to Some Functions for Oracle Data Mining Model Build Configuration and Text Processing
The new arguments for some of the data mining model functions are:
odm.setting
ctx.setting
odm.setting
The odm.setting value is a list that specifies Oracle Data Mining parameter settings. Both Oracle Data Mining global and algorithm-specific parameters can be specified to configure the model build. Some new features are enabled through the parameter settings. For example, you can use this argument to specify the creation of a partitioned model, which is an ensemble model that consists of multiple sub-models. When you specify the parameter ODMS_PARTITION_COLUMNS and the names of the columns by which to partition the input data, the function returns a model with a sub-model for each partition. The partitions are based on the unique values found in the columns.
Partitioned models can automate scoring by allowing you to reference the top-level model only, which causes the proper sub-model to be chosen based on the values of the partitioned column or columns for each row of data to be scored.
ctx.setting
With this argument, you can specify Oracle Text attribute-specific settings. You specify the columns that should be treated as text and the type of text transformation to apply.
This argument applies to the following functions:
ore.odmESA, Explicit Semantic Analysis
ore.odmGLM, Generalized Linear Models
ore.odmKMeans, k-Means
ore.odmNMF, Non-Negative Matrix Factorization
ore.odmSVD, Singular Value Decomposition
ore.odmSVM, Support Vector Machines
Note:
To create an Oracle Text policy, the user must have theCTXSYS.CTX_DDL privilege.Related Topics
Parent topic: New Features for Oracle Database Release 12.2.0.1
Oracle R Enterprise Release 1.5.1 has the following other changes, which are in effect for Oracle Database 12c Release 12.2.0.1 and earlier releases.
Updated supporting packages DBI and ROracle
Requirement for R 3.3.0; as with earlier releases of Oracle R Enterprise, Oracle recommends that you use Oracle R Distribution
A new RPM for Oracle R Distribution, R-core-extra-3.3.0-1.el6.x86_64.rpm
R-3.3.0 depends on newer versions of several third party compression libraries and no longer contains bundled copies of them. This means that R 3.3.0 won't build against Linux 6 as is, because the native versions of these libraries are older than those that R-3.3.0 requires.
The R-core-extra RPM contains the required versions of these libraries and is provided as a convenience for users of Oracle Linux 6. Adding the location of the libraries in R-core-extra to LD_LIBRARY_PATH removes the need to built these libraries separately. Oracle Linux 7 introduces the required versions of these libraries, but the R-core-extra RPM is provided as a convenience if needed.
