# Mode

Sometimes it is useful to look at the the most frequent value in a data set, known as the 'mode'. R doesn't have a standard function for mode, but we can calculate the mode easily using the `table()`

function, which you might be familiar with now.

When you have a large data set, the output of `table()`

might be too long to manually identify which value is the mode. In this case it can be useful to use the `sort()`

function, which arranges a vector or factor into ascending order. (You can add the argument `decreasing = TRUE`

to `sort()`

if you want to arrange it in to descending order.)

Lets use `sort()`

and `table()`

to find the mode of the `carb`

variable of `mtcars`

.

- Produce a frequency table of
`carb`

from`mtcars`

in descending order of frequency - Remember that you should separate arguments with a comma
