getMaxIndexOfRows {BBmisc} | R Documentation |

## Find row- or columnwise the index of the maximal / minimal element in a matrix.

### Description

`getMaxIndexOfRows`

returns the index of the maximal element of each row.
`getMinIndexOfRows`

returns the index of the minimal element of each row.
`getMaxIndexOfCols`

returns the index of the maximal element of each col.
`getMinIndexOfCols`

returns the index of the minimal element of each col.
If a corresponding vector (row or col) is empty, possibly after NA removal, -1 is returned
as index.

### Usage

```
getMaxIndexOfRows(x, weights = NULL, ties.method = "random", na.rm = FALSE)
getMinIndexOfRows(x, weights = NULL, ties.method = "random", na.rm = FALSE)
getMaxIndexOfCols(x, weights = NULL, ties.method = "random", na.rm = FALSE)
getMinIndexOfCols(x, weights = NULL, ties.method = "random", na.rm = FALSE)
```

### Arguments

### Value
