Merges intervals by returning an index vector specifying the (first)
interval that each value maps to, if any.
# S3 method for numeric
mergeIntervals(intervals, ...)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.
Henrik Bengtsson
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}.
