## Usage

```
mean_sd(x, times = 1L, remove_na = TRUE, named = TRUE, na.rm = TRUE, ...)
median_mad(
x,
times = 1L,
remove_na = TRUE,
constant = 1.4826,
named = TRUE,
na.rm = TRUE,
...
)
```

## Arguments

- x
A numeric vector (or one that can be coerced to one via

`as.numeric()`

) to be summarized.- times
How many SDs above and below the Mean (or MADs around the Median)

- remove_na
Logical. Should

`NA`

) or not (`FALSE`

, default)?- named
Should the vector be named? (E.g.,
