In R, a column vector can be defined using the `c()` function and the `matrix()` function. Here are the steps to define the column vector a = (0 7):

Step 1: Open R or RStudio.

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

```R
a_elements

Question

In R, a column vector can be defined using the `c()` function and the `matrix()` function. Here are the steps to define the column vector a = (0 7):

Step 1: Open R or RStudio.

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

```R
a_elements <- c(0, 7)
```

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

```R
a <- matrix(a_elements, nrow=2, ncol=1)
```

In this command, `nrow=2` specifies that the matrix should have 2 rows, and `ncol=1` specifies that the matrix should have 1 column. This creates a column vector.

Step 4: Print the column vector.

```R
print(a)
```

This will output:

```R
     [,1]
[1,]    0
[2,]    7
```

This indicates that the column vector a = (0 7) has been successfully defined in R.
