How to create a Three Dimensional Vector in R

How to create a Three Dimensional Vector in R ?

Answer

To create a three-dimensional vector in R, you can use the array function.


✐ Examples

1 Create a Numeric Three-Dimensional Vector

In this example,

  1. We use the array function to create a three-dimensional vector.
  2. We specify the dimensions of the vector using the dim parameter.
  3. We assign values to the elements of the vector.

R Program

# Step 1: Create a numeric three-dimensional vector
array_data <- array(data = c(1, 2, 3, 4, 5, 6, 7, 8, 9),
                     dim = c(3, 3, 3))

# Step 2: Print the vector
print(array_data)

Output

 , , 1

     [,1] [,2] [,3]
[1,]    1    4    7
[2,]    2    5    8
[3,]    3    6    9

 , , 2

     [,1] [,2] [,3]
[1,]    1    4    7
[2,]    2    5    8
[3,]    3    6    9

 , , 3

     [,1] [,2] [,3]
[1,]    1    4    7
[2,]    2    5    8
[3,]    3    6    9

2 Create a String Three-Dimensional Vector

In this example,

  1. We use the array function to create a three-dimensional vector.
  2. We specify the dimensions of the vector using the dim parameter.
  3. We assign values to the elements of the vector.

R Program

# Step 1: Create a string three-dimensional vector
array_data <- array(data = c("a", "b", "c", "d", "e", "f", "g", "h", "i"),
                     dim = c(3, 3, 3))

# Step 2: Print the vector
print(array_data)

Output

 , , 1

     [,1] [,2] [,3]
[1,] "a" "d" "g"
[2,] "b" "e" "h"
[3,] "c" "f" "i"

 , , 2

     [,1] [,2] [,3]
[1,] "a" "d" "g"
[2,] "b" "e" "h"
[3,] "c" "f" "i"

 , , 3

     [,1] [,2] [,3]
[1,] "a" "d" "g"
[2,] "b" "e" "h"
[3,] "c" "f" "i"
