How to create a List in R?

R – Create List

To create a list in R programming, call list() function. We may pass initial values for the list items to this list() function as arguments.

In this tutorial, we will learn how to create a list in R, using list() function, with the help of example programs.

The syntax to create a list in R is

</>

Copy

myList <- list(item1, item2, item3)

list() function returns a new list formed with the items given, and is stored in myList.

A list can contain elements of any type, and is mutable.

In the following program, we will create a list containing some string values using list() function.

example.R

</>

Copy

myList <- list("Sunday", "Monday", "Tuesday", "Wednesday")
print(myList)

Output

[[1]]
[1] "Sunday"

[[2]]
[1] "Monday"

[[3]]
[1] "Tuesday"

[[4]]
[1] "Wednesday"

Now, let us create a list containing some numbers and string values.

example.R

</>

Copy

myList <- list(25, "Hello World")
print(myList)

Output

[[1]]
[1] 25

[[2]]
[1] "Hello World"

In this R Tutorial, we learned how to create a list with initial values in R programming using list() function, with the help of examples.
