which_min {mlr3misc} | R Documentation |

## Index of the Minimum/Maximum Value, with Correction for Ties

### Description

Works similar to `base::which.min()`

/`base::which.max()`

, but corrects for ties.
Missing values are treated as `Inf`

for `which_min`

and as `-Inf`

for `which_max()`

.

### Usage

```
which_min(x, ties_method = "random", na_rm = FALSE)
which_max(x, ties_method = "random", na_rm = FALSE)
```

### Arguments

`x` |
( |

`ties_method` |
( |

`na_rm` |
( |

### Value

(`integer()`

): Index of the minimum/maximum value.
Returns an empty integer vector for empty input vectors and vectors with no non-missing values
(if `na_rm`

is `TRUE`

).
Returns `NA`

if `na_rm`

is `FALSE`

and at least one `NA`

is found in `x`

.

### Examples

```
x = c(2, 3, 1, 3, 5, 1, 1)
which_min(x, ties_method = "first")
which_min(x, ties_method = "last")
which_min(x, ties_method = "random")
which_max(x)
which_max(integer(0))
which_max(NA)
which_max(c(NA, 1))
```
