In R, you can define a matrix using the `matrix()` function. Here are the steps to define the 2x2 matrix B = (1 4, 3 2):

Step 1: Open R or RStudio.

Step 2: Define the elements of the matrix using the `c()` function. The `c()` function combines its arguments to form a vector.

```R
b_elements

Question

In R, you can define a matrix using the `matrix()` function. Here are the steps to define the 2x2 matrix B = (1 4, 3 2):

Step 1: Open R or RStudio.

Step 2: Define the elements of the matrix using the `c()` function. The `c()` function combines its arguments to form a vector.

```R
b_elements <- c(1, 3, 4, 2)
```

Step 3: Convert the vector to a matrix using the `matrix()` function. The `matrix()` function creates a matrix from the given set of values.

```R
B <- matrix(b_elements, nrow=2, ncol=2, byrow = TRUE)
```

In this command, `nrow=2` specifies that the matrix should have 2 rows, and `ncol=2` specifies that the matrix should have 2 columns. The `byrow = TRUE` argument specifies that the matrix should be filled by rows.

Step 4: Print the matrix.

```R
print(B)
```

This will output:

```R
     [,1] [,2]
[1,]    1    4
[2,]    3    2
```

This indicates that the 2x2 matrix B = (1 4, 3 2) has been successfully defined in R.
