distance_to_nearest | R Documentation |

For each point or interval in the `from`

argument, compute the
distance to the nearest position in the `to`

argument.

```
## S4 method for signature
## 'Intervals_virtual_or_numeric,Intervals_virtual_or_numeric'
distance_to_nearest(from, to, check_valid = TRUE)
```

`from` |
An object of appropriate type. |

`to` |
An object of appropriate type. |

`check_valid` |
Should |

A vector of distances, with one entry per point or interval in
`from`

. Any intervals in `from`

which are either empty (see
`empty`

) or have `NA`

endpoints produce a `NA`

result.

This function is now just a wrapper for `which_nearest`

.

See `which_nearest`

, which also returns indices for the
interval or intervals (in case of ties) at the distance reported.

```
# Point to interval
to <- Intervals( c(0,5,3,Inf) )
from <- -5:10
plot( from, distance_to_nearest( from, to ), type = "l" )
segments( to[,1], 1, pmin(to[,2], par("usr")[2]), 1, col = "red" )
# Interval to interval
from <- Intervals( c(-Inf,-Inf,3.5,-1,1,4) )
distance_to_nearest( from, to )
```
