Merges intervals

Merges intervals by returning an index vector specifying the (first) interval that each value maps to, if any.

Usage
# S3 method for 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 bounds of each interval. If a numeric vector of length 2N, each consecutive pair should be the lower and upper bounds of an interval.

Not used.

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}.

Value

Returns a matrix (or a vector) of M intervals, where M <= N. The intervals are ordered by their lower bounds. The @mode of the returned intervals is the same as the mode of the input intervals.
