Merges intervals

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

Keywords: methods, utilities, programming

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
...: 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.="" @mode="" of="" returned="" is="" same="" as="" mode="" input="" intervals.<="" li="">
