Create a 3x3x2 Array in R using two Vectors

Last update on June 04 2025 12:51:03 (UTC/GMT +8 hours)

Write a R program to create an array with three columns, three rows, and two "tables", taking two vectors as input to the array. Print the array.

Sample Solution :

R Programming Code :

# Create a vector with elements 1, 3, 5, and 7
v1 = c(1, 3, 5, 7)

# Create a vector with elements 2, 4, 6, 8, and 10
v2 = c(2, 4, 6, 8, 10)

# Combine vectors v1 and v2 into a single array with dimensions 3x3x2
# The array will have 3 rows, 3 columns, and 2 "tables"
arra1 = array(c(v1, v2), dim = c(3, 3, 2))

# Print the content of the array
print(arra1)

Output:

, , 1

     [,1] [,2] [,3]
[1,]    1    7    6
[2,]    3    2    8
[3,]    5    4   10

, , 2

     [,1] [,2] [,3]
[1,]    1    7    6
[2,]    3    2    8
[3,]    5    4   10                         

Explanation:

• Create Vectors:
• v1 = c(1, 3, 5, 7): Creates a vector v1 with the values 1, 3, 5, and 7.
• v2 = c(2, 4, 6, 8, 10): Creates a vector v2 with the values 2, 4, 6, 8, and 10.
• Combine Vectors into an Array:
• array(c(v1, v2), dim = c(3, 3, 2)): Combines v1 and v2 into a single vector and reshapes it into a 3-dimensional array with dimensions 3x3x2.
• c(v1, v2): Concatenates v1 and v2 into one vector.
• dim = c(3, 3, 2): Specifies the dimensions of the array (3 rows, 3 columns, and 2 tables).
• Print the Array:
• print(arra1): Outputs the contents of the array to the console. The array will have two 3x3 matrices (tables), with each matrix filled with the concatenated values from v1 and v2.
