Summary

## Instruction

Nice work! To create a vector, you need to define the values it will contain. You do so with the c() function. For the function arguments, you can include as many comma-separated values as you'd like in your vector:

c(1, 2, 3, 4)

Here we defined a vector that contains four numbers: 1, 2, 3, and 4.

You can assign a vector to a variable like this:

salaries <- c(3400, 2800, 5600, 4200, 3100, 3800, 2700, 6100, 6200, 2400, 1800, 2600)


We've created a vector called salaries that stores the 12 values (salaries) that we specified inside the c() function.

## Exercise

We'd like to analyze salaries by department. Versico has four departments that vary in the number of employees they have. In this case, there are 4, 3, 2, and 3 employees in these four departments. Create a vector named department_employees that contains the numbers of employees in each department, in this precise order.

### Stuck? Here's a hint!

You should write:

department_employees <- c(4, 3, 2, 3)
