Returns all possible rankings that extend a partial ranking.

## Arguments

- data
List as returned by exact_rank_prob when run with

`only.results = FALSE`

- force
Logical scalar. Stops function if the number of rankings is too large. Only change to TRUE if you know what you are doing

## Details

The `i`

th row of the matrix contains the rank of node `i`

in all possible rankings
that are in accordance with the partial ranking `P`

. The lowest rank possible is
associated with `1`

.

## Examples

```
P <- matrix(c(0, 0, 1, 1, 1, 0, 0, 0, 1, 0, 0, 0, 0, 0, 1, rep(0, 10)), 5, 5, byrow = TRUE)
P
#> [,1] [,2] [,3] [,4] [,5]
#> [1,] 0 0 1 1 1
#> [2,] 0 0 0 1 0
#> [3,] 0 0 0 0 1
#> [4,] 0 0 0 0 0
#> [5,] 0 0 0 0 0
res <- exact_rank_prob(P, only.results = FALSE)
get_rankings(res)
#> [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9]
#> [1,] 1 1 2 1 1 1 2 1 2
#> [2,] 3 2 1 4 3 2 1 2 1
#> [3,] 2 3 3 2 2 3 3 4 4
#> [4,] 5 5 5 5 4 4 4 3 3
#> [5,] 4 4 4 3 5 5 5 5 5
