### Formatting Helper Functions

The fmtr package also contains several formatting helper functions. These functions help with common formatting styles seen in statistical reports. For example, a range from 1 to 10 is commonly displayed as “1 - 10”, with a hyphen separating the minimum from the maximum. To accomplish this formatting easily, the package provides a `fmt_range()` function that both calculates the range and formats it in the desired manner.

Below is a complete list of the formatting helper functions. See the help documentation for additional details:

- `fmt_range()`
- `fmt_n()`
- `fmt_quantile_range()`
- `fmt_median()`
- `fmt_cnt_pct()`
- `fmt_mean_sd()`
- `fmt_mean_stderr()`
