This chapter gave you an overview of the R language. You learned the basics, including how to write R expressions and create variables. The chapter introduced the data structures in R, with an emphasis on the most important one, the data frame. You saw how to read the data from SQL Server, store it in a data frame, and then retrieve it from the data frame. In Chapter 3, Getting Familiar with Python, before doing some additional manipulation of the data in a data frame to prepare it for further analysis, we will have a short introduction to the Python language.
