Create a 3D Array of 24 Elements using the dim() Function in R

R Programming: Array Exercise-3 with Solution

Write a R program to create an 3 dimensional array of 24 elements using the dim() function.

Sample Solution :

R Programming Code :

# Generate a vector 'v' with 24 random integers between 1 and 5, allowing replacement
v = sample(1:5, 24, replace = TRUE)

# Reshape the vector 'v' into a 3-dimensional array with dimensions 3x2x4
dim(v) = c(3, 2, 4)

# Print a message indicating the output is a 3-dimensional array
print("3-dimension array:")

# Display the contents of the 3-dimensional array
print(v)

Output:

[1] "3-dimension array:"
, , 1

     [,1] [,2]
[1,]    4    2
[2,]    4    2
[3,]    2    1

, , 2

     [,1] [,2]
[1,]    4    2
[2,]    2    4
[3,]    2    4

, , 3

     [,1] [,2]
[1,]    4    2
[2,]    1    5
[3,]    3    2

, , 4

     [,1] [,2]
[1,]    3    3
[2,]    1    5
[3,]    1    2                         

Explanation:

• Generate Random Numbers: Creates a vector v with 24 random integers sampled from 1 to 5, with replacement allowed.
• Set Dimensions: Reshapes the vector v into a 3-dimensional array with dimensions 3x2x4.
• Print Message: Displays a message indicating that the following output is a 3-dimensional array.
• Print Array: Outputs the contents of the 3-dimensional array v.
