As you move from practicing
R basics to interacting with data, you will need to understand how that data is stored, and to carefully consider the appropriate structure for the organization, analysis, and visualization of your data. This chapter covers the foundational concepts for working with vectors in
R. Vectors are the fundamental data type in
R, so understanding these concepts is key to effectively programming in the language. This chapter discusses how
R stores information in vectors, the way in which operations are executed in vectorized form, and how to extract data from vectors.
7.1 What Is a Vector?
Vectors are one-dimensional collections of values that are all stored in a single variable. For example, you can make a vector ...
