R Programming: Create a Blank Matrix

R Programming: Matrix Exercise-1 with Solution

Write a R program to create a blank matrix.

Sample Solution:

R Programming Code:

# Create a blank matrix with 10 rows and 5 columns
m = matrix(, nrow = 10, ncol = 5)

# Print a message describing the matrix
print("Empty matrix of 10 rows and 5 columns:")

# Print the created empty matrix
print(m)

Output:

[1] "Empty matrix of 10 rows and 5 columns:"
      [,1] [,2] [,3] [,4] [,5]
 [1,]   NA   NA   NA   NA   NA
 [2,]   NA   NA   NA   NA   NA
 [3,]   NA   NA   NA   NA   NA
 [4,]   NA   NA   NA   NA   NA
 [5,]   NA   NA   NA   NA   NA
 [6,]   NA   NA   NA   NA   NA
 [7,]   NA   NA   NA   NA   NA
 [8,]   NA   NA   NA   NA   NA
 [9,]   NA   NA   NA   NA   NA
[10,]   NA   NA   NA   NA   NA                     

Explanation:

• m = matrix(, nrow = 10, ncol = 5): Creates a blank matrix named m with 10 rows and 5 columns. The matrix is filled with NA (missing) values by default.
• print("Empty matrix of 10 rows and 5 columns:"): Prints a descriptive message about the matrix.
• print(m): Displays the contents of the matrix m, showing 10 rows and 5 columns filled with NA values.
