# Developer function for handling missing values in new metrics

Source:`R/missings.R`

`yardstick_remove_missing.Rd`

`yardstick_remove_missing()`

, and `yardstick_any_missing()`

are useful
alongside the metric-summarizers functions for implementing new custom
metrics. `yardstick_remove_missing()`

removes any observations that contains
missing values across, `truth`

, `estimate`

and `case_weights`

.
`yardstick_any_missing()`

returns `FALSE`

if there is any missing values in
the inputs.

## Usage

```
yardstick_remove_missing(truth, estimate, case_weights)
yardstick_any_missing(truth, estimate, case_weights)
```

## Arguments

- truth, estimate
Vectors of the same length.

- case_weights
A vector of the same length as

`truth`

and`estimate`

, or`NULL`

if case weights are not being used.
