6.8 List in r Programming
A list in R is a type of R object that contains different types of elements like—numbers, vectors, strings, and another
list within it. A list can also contain a function, a matrix, or data frames as its elements.
To create a list, we use the list() function. An example is shown below to create a list using strings, numbers, vectors,
and logical values.
Example
Enter the following code snippet:
# list containing strings, numbers, vectors and a logical
list_data <- list("Red", "White", c(1,2,3), TRUE, 22.4)
print(list_data)
6.8.1 name elements of a List
Matrix: It is a collection of elements of the same type arranged into a fixed number of rows and columns. So, it is
two-dimensional in nature.
With the help of an example, we will now learn to name the R list elements. Let’s create a list containing a vector,
matrix, and list.
Example
Enter the following code snippet:
