# Naming a matrix

To help you remember what is stored in `star_wars_matrix`

, you would like to add the names of the movies for the rows. Not only does this help you to read the data, but it is also useful to select certain elements from the matrix.

Similar to vectors, you can add names for the rows and the columns of a matrix

```
rownames(my_matrix) <- row_names_vector
colnames(my_matrix) <- col_names_vector
```

We went ahead and prepared two vectors for you: `region`

, and `titles`

. You will need these vectors to name the columns and rows of `star_wars_matrix`

, respectively.
