3. Basic Concepts What is R? CRAN RStudio
8/21/ :10 PM
Basic Concepts
What is R?
Programming language dedicated to statistical analysis
Basic and advanced graphical/plotting techniques
Leading choice for data science projects
CRAN
Comprehensive R Archive Network
Download for the base R system and packages
Similar to the Hive Language Manual for Hive or Books Online for SQL Server
RStudio
IDE for R Development
Downloaded from
Free open source software language
On version 3.2.0
R provides a wide variety of statistical (linear and nonlinear modeling, classical statistical tests, time-series analysis, classification, clustering, …) and graphical techniques, and is highly extensible.
According to Revolution R study –
Object Oriented Language
Hive Language Manual
Many different packages that are available outside of the base package

5. What is AzureML? Cloud-Based Predictive Analytics Service
8/21/ :10 PM
What is AzureML?
Cloud-Based Predictive Analytics Service
Includes multiple algorithms for regression, classification, clustering, etc.
Access data from multiple types of data sources
Easy to evaluate model performance
Easy to Deploy Predictive Models
Deploy experiments as a web service
Provides API Key and sample code to call the web service
Publish to the Azure Marketplace as paid or free services
AzureML Studio
Allows users to develop AzureML Experiments
Cloud-Based Predictive Analytics Service
Regression – Neural Networks, linear regression
Classification – Decision trees, boosted decision trees
Clustering – K-Means Clustering
Can be used to create customer churn models, customer segmentation models, customer propensity models, recommendation engines, etc.
.txt/.csv
Zip files
Azure blob, table or SQL database
Hive tables
R object or workspace file
Evaluate Model module creates a  receiver operating characteristic (ROC) curve to plot the rates of true positives to false positives, a Lift curve to that shows the number of true positives vs. the positive rate, a precision vs. recall chart and a confusion matrix
Easy to Deploy Predictive Models
Ready-to-consume web services
Convert training experiments to predictive analytics then you can publish as a web service
The Azure Marketplace provides the ability to publish Azure Machine Learning web services as paid or free services for consumption by external customers.

6. AzureML & R Analytics in AzureML can be extended by using R
8/21/ :10 PM
AzureML & R
Analytics in AzureML can be extended by using R
Execute R Script module
Accepts multiple input datasets and outputs a single dataset
Author and Deploy Custom R Modules
Instead of using an Execute R Script module, a user can create a custom module that executes a user-defined R function
Only available in the workspace in which it was created
Publish R Code as a Web Service
Example of how AzureML can operationalize R scripts
AzureML R Web Services
Use the execute R script module to utilize R scripts in an azureml experiment.
Web services can include services such as calculators, text-analysis engines and can be used through a mobile app or a website

8. Plotting Graphs in R Base Graphs Lattice Graphs ggplot2
8/21/ :10 PM
Plotting Graphs in R
Base Graphs
Basic plotting functionality
Plot()
Lattice Graphs
Plots are created with a single function call (i.e. histograms, boxplots, etc.)
Most useful for conditioning types of plots
Good for putting many plots on a screen
ggplot2
Library of plotting options in R
Splits the difference between base and lattice
Basic ggplot2 function is qplot()
Lattice is good to see how y changes over x with different numbers of values
ggplot2 is an implementation of the grammar of graphics
ggplot automatically deals with spacing, text, titles, while still allowing you to customize
Think of qplot as quick plot. Other ggplot graphs include ggplot and autoplot

10. Revolution R Recent Microsoft Acquisition Enterprise-Ready Performance
8/21/ :10 PM
Revolution R
Recent Microsoft Acquisition
Enterprise-Ready Performance
Multi-threaded processing using Intel’s Math Kernel Library
42 times faster than any SAS technology
Integration in Azure and SQL Server On-Premises
HDInsight and AzureML
SQL Server 2016
Utilize and Build Upon Revolution’s Open Source Projects
ParallelR collection of packages for distributed programming
Rhadoop for running R on Hadoop nodes
DeployR for deploying R analytics in web and dashboard applications
Official as of April 2015
Revolution R has been able to make the R platform enterprise ready
“We will also continue to support running Revolution R Enterprise across heterogeneous platforms including Linux, Teradata and Hadoop deployments.”
“For example, we will build R into SQL Server to provide enormously fast and scalable in-database analytics that can be deployed in an enterprise customer’s datacenter, on Azure, or in a hybrid combination”
