R Programming: Convert a Matrix to a 1 Dimensional Array

Last update on June 04 2025 12:49:51 (UTC/GMT +8 hours)

Write a R program to convert a given matrix to a 1 dimensional array.

Sample Solution :

R Programming Code :

 # Create a matrix 'm' with 3 rows and 4 columns filled with values from 1 to 12
m = matrix(1:12, 3, 4)

# Print a message indicating the original matrix
print("Original matrix:")

# Display the original matrix
print(m)

# Convert the matrix 'm' to a 1-dimensional array
a = as.vector(m)

# Print a message indicating the 1-dimensional array
print("1 dimensional array:")

# Display the 1-dimensional array
print(a)

Output:

[1] "Original matrix:"
     [,1] [,2] [,3] [,4]
[1,]    1    4    7   10
[2,]    2    5    8   11
[3,]    3    6    9   12
[1] "1 dimensional array:"
 [1]  1  2  3  4  5  6  7  8  9 10 11 12

Explanation:

m=matrix(1:12,3,4): Creates a matrix m with 3 rows and 4 columns, filled with values from 1 to 12.
print("Original matrix:"): Prints a message indicating the start of the matrix display.
print(m): Displays the original matrix m.
a = as.vector(m): Converts the matrix m into a 1-dimensional array a.
print("1 dimensional array:"): Prints a message indicating the start of the array display.
print(a): Displays the 1-dimensional array a obtained from the matrix.
