Understanding Lists
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
1list("Text", 42, TRUE)
The structure of the list output differs from that of a vector, since each element is displayed with its index in double brackets.
