# 1. Introduction

This R program creates three individual vectors, each containing three integers, and then combines these vectors into a 3x3 matrix. Each column of the matrix represents one of the vectors.

# 2. Program Steps

1. Create three vectors, a, b, and c, each containing three integers.

2. Combine these vectors into a 3x3 matrix.

3. Print the content of the resulting matrix.

# 3. Code Program

``````# Step 1: Create three vectors with three integers each
a <- c(1, 2, 3)  # First vector
b <- c(4, 5, 6)  # Second vector
c <- c(7, 8, 9)  # Third vector

# Step 2: Combine the vectors to form a 3x3 matrix
matrix_3x3 <- cbind(a, b, c)

# Step 3: Print the matrix
print("3x3 Matrix:")
print(matrix_3x3)
``````

### Output:

```3x3 Matrix:
a b c
[1,] 1 4 7
[2,] 2 5 8
[3,] 3 6 9
```

### Explanation:

1. a <- c(1, 2, 3): Initializes the first vector a with integers 1, 2, and 3.

2. b <- c(4, 5, 6): Initializes the second vector b with integers 4, 5, and 6.

3. c <- c(7, 8, 9): Initializes the third vector c with integers 7, 8, and 9.

4. cbind(a, b, c): Combines the vectors a, b, and c into a 3x3 matrix. Each vector becomes a column in the matrix.

5. print("3x3 Matrix:"): Prints a message indicating that the following output is a 3x3 matrix.

6. print(matrix_3x3): Displays the content of the 3x3 matrix.
