How to create a list of elements using vectors, matrices, and a functions

Here we are explaining how to write an R program to create a list of elements using vectors, matrices, and functions. Here we are using a built-in function list() for this. This function helps to create a list. The syntax of this function is

list(…)

– where ….(dots)are the objects, possibly named.

How to create a list of elements using vectors, matrices, and functions using R program

Below are the steps used in the R program to create a list of elements using vectors, matrices, and functions. In this R program, we directly give the values to a built-in function list(). Here we are using variables L for holding the list elements. Call the function list() with different types of elements. Here month.abb is the three-letter abbreviations for the English month names. And asin helps to find the sine inverse of the given value. The returned angle is in the range -pi/2 through pi/2.Finally, print the list content.

ALGORITHM

STEP 1: Assign variables L with a lists STEP 2: include list of vectors STEP 3 include list of months as month.abb STEP 4: include list of matrix as matrix(c(3, -8, 1, -3), nrow = 2) STEP 5: include sine inverse of value as asin STEP 6: Finally print the list contents

R Source Code

L = list(
          c(1, 2, 3, 4, 5, 6),  
          month.abb,
          matrix(c(3, -8, 1, -3), nrow = 2),
          asin
)

print("Content of the list:")

## [1] "Content of the list:"

print(L)

## [[1]]
## [1] 1 2 3 4 5 6
## 
## [[2]]
##  [1] "Jan" "Feb" "Mar" "Apr" "May" "Jun" "Jul" "Aug" "Sep" "Oct" "Nov" "Dec"
## 
## [[3]]
##      [,1] [,2]
## [1,]    3    1
## [2,]   -8   -3
## 
## [[4]]
## function (x)  .Primitive("asin")
