distance_to_nearest {intervals} | R Documentation |
Compute distance to nearest position in a set of intervals
Description
For each point or interval in the from
argument, compute the
distance to the nearest position in the to
argument.
Usage
## S4 method for signature
## 'Intervals_virtual_or_numeric,Intervals_virtual_or_numeric'
distance_to_nearest(from, to, check_valid = TRUE)
Arguments
from |
An object of appropriate type. |
to |
An object of appropriate type. |
check_valid |
Should |
Value
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.
Note
This function is now just a wrapper for which_nearest
.
See Also
See which_nearest
, which also returns indices for the
interval or intervals (in case of ties) at the distance reported.
Examples
# 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 )
