Data munging in R can be done independently without using SQL Server. The following diagram illustrates a recommended high-level process that developers can follow when using SQL Server and R. If you have worked in R before, you are likely familiar with steps 2, 3, and 5 performed in R directly.
Please note that Steps 3 and 4 are optional and will be discussed more in Chapter 6, Predictive Modeling and Chapter 7, Operationalizing R Code:

Let's get started with Data Munging in R. Specifically, in this section, we will be working with the R environment so that we know how it works in R before we stitch it together with T-SQL. If you are familiar with R, you may skip this section. Following are prerequisites for this section:
- An R IDE, for example RTVS...
