# Labeling Vectors

Now that you're familiar with creating vectors, let's apply them to store and label valuable information, such as grades on a scale from `1` to `100`. However, the grades alone may not be self-explanatory to someone else.

Suppose the grades are as follows:

Math 80
Physics 75
English 95
Literature 100

While you know how to create a vector with grades, the next step is labeling those values with their corresponding subjects. This can be done by assigning a vector of names to `names(vector)`, where `vector` is your original vector that you wish to label.

Here's how you can do that:

Here, `c('Math', 'Physics', 'English', 'Literature')` is the vector of names (labels). As you can see, using this approach, we can present the information more clearly.

Tarefa

Imagine you manage a local furniture store. You have a list of items and their respective prices, as shown below:

 Item Price Sofa \$340 Armchair \$150 Dining table \$115 Dining chair \$45 Bookshelf \$160

Your task is to store the prices in a vector named `prices` and label each price with the corresponding item.

1. Construct a vector of prices and store it in the variable `prices`.
2. Use the variable `items` to assign names to the elements in the `prices` vector.
3. Display the `prices` vector.
