mergeIntervals.numeric: Merges intervals
Description
Merges intervals by returning an index vector specifying the (first)
interval that each value maps to, if any.Usage
## S3 method for class 'numeric':
mergeIntervals(intervals, ...)
Arguments
intervals
The N intervals to be merged.
If an Nx2 numeric matrix, the first column should be the lower
bounds and the second column the upper boun Value
- Returns a
matrix (or a vector) of M intervals, where M <= n.="" the="" intervals="" are="" ordered="" by="" their="" lower="" bounds.="" @mode="" of="" returned="" is="" same="" as="" mode="" input="" intervals.<="" li="">
Details
The upper and lower bounds are considered to be inclusive, that is,
all intervals are interpreted to be of form [a,b].
There is currently no way to specify intervals with open bounds,
e.g. (a,b].
Furthermore, the bounds are currently treated as real values.
For instance, merging [0,1] and [2,3] will return the same intervals.
Note, if integer intervals were treated specially, we would merge
these intervals to integer interval [0,3] == {0,1,2,3}.
