bookUnderstanding Lists

Note
Definition

A list is a flexible data type that, unlike a vector, can store elements of different types in a single object.

Creating List

To create a list, use the list() function and pass the values you want to store as arguments. You can even store a text string, a number, and a logical value together.

Example

1
list("Text", 42, TRUE)
copy

The structure of the list output differs from that of a vector, since each element is displayed with its index in double brackets.

Tehtävä

Swipe to start coding

  1. Create a list named info with the information on the current chapter and course: 'R Introduction', 6 (section), 1 (chapter in the section), 41 (chapter overall).
  2. Output the value of this list.
