Summary

In this chapter, we examined some of the data types available in the R environment. These include discrete data types such as integers and factors. It also includes continuous data types such as real and complex data types. We also examined ways to test a variable to determine what type it is.

In the next chapter, we look at the data structures that can be used to keep track of data. This includes vectors and data types such as lists and data frames that can be constructed from vectors.
