Overview of this book

R Services was one of the most anticipated features in SQL Server 2016, improved significantly and rebranded as SQL Server 2017 Machine Learning Services. Prior to SQL Server 2016, many developers and data scientists were already using R to connect to SQL Server in siloed environments that left a lot to be desired, in order to do additional data analysis, superseding SSAS Data Mining or additional CLR programming functions. With R integrated within SQL Server 2017, these developers and data scientists can now benefit from its integrated, effective, efficient, and more streamlined analytics environment. This book gives you foundational knowledge and insights to help you understand SQL Server 2017 Machine Learning Services with R. First and foremost, the book provides practical examples on how to implement, use, and understand SQL Server and R integration in corporate environments, and also provides explanations and underlying motivations. It covers installing Machine Learning Services;maintaining, deploying, and managing code;and monitoring your services. Delving more deeply into predictive modeling and the RevoScaleR package, this book also provides insights into operationalizing code and exploring and visualizing data. To complete the journey, this book covers the new features in SQL Server 2017 and how they are compatible with R, amplifying their combined power.

Advanced predictive algorithms and analytics

So far, we have examined the data preparation and data exploration functions available in the RevoScaleR package. Besides these functions, predicting classification or regression problems can also be done, especially when dealing with large datasets.

I will mention only few of these. The complete list is available online (https://docs.microsoft.com/en-us/machine-learning-server/r-reference/revoscaler/revoscaler) and some of the points are as follows:

  • rxLinMod: This is used for building and predicting a linear model
  • rxLogit: This is used for building and predicting the logistic regression model
  • rxGlm: This is used for creating a generalized linear model
  • rxDTree: This is used for creating a classification or regression tree
  • rxBTrees: This is used for building a classification or regression decision forest—that is using a stochastic...
