Summary
In this chapter, you learned the basics of the R language. You learned data structures in R (especially the most important one, the data frame) and how to do simple data manipulation. Then you saw some of the capabilities of R by creating graphical visualizations and calculating descriptive statistics in order to get a deeper understanding of your data. Finally, you got a comprehensive view of R integration in SQL Server. The next chapter, Chapter 14, Data Exploration and Predictive Modeling with R in SQL Server, continues the story and gives you more in-depth knowledge about some of the most important data mining and machine learning algorithms and tasks.
