Data structures

Create, modify, and subset vectors, lists, and data frames

All data in R are vectors, but there are some special forms of vectors such as lists and data frames. We’ll explore how to create, modify, and subset vectors, lists, and data frames.

Learning objectives

• Create vectors, lists, and data frames
• Learn how to subset data
• View attributes of data
