add a missing variable which is present as a column but not as a row, create this row as a row of zeros in a matrix in r

# Creating a matrix
my_matrix <- matrix(c(1, 2, 3, 4), nrow = 2, ncol = 2, byrow = TRUE)

# Print the original matrix
print(my_matrix)

# Adding a missing variable as a row of zeros
my_matrix <- rbind(my_matrix, c(0, 0))

# Print the updated matrix with missing variable added as a row of zeros
print(my_matrix)
