If 'intervals.set.out' is 'NULL' a data frame representing the
intervals.
Arguments
intervals
two-dimensional intervals
band
track expression band. If 'NULL' no band is used.
intervals.set.out
intervals set name where the function result is
optionally outputted
Details
This function intersects each two-dimensional interval from 'intervals' with
'band'. If the intersection is not empty, the interval is shrunk to the
minimal rectangle that contains the band and added to the return value.
If 'intervals.set.out' is not 'NULL' the result is saved as an intervals
set. Use this parameter if the result size exceeds the limits of the
physical memory.
