gintervals.quantiles {misha} | R Documentation |
Calculates quantiles of a track expression for intervals
Description
Calculates quantiles of a track expression for intervals.
Usage
gintervals.quantiles(
expr = NULL,
percentiles = 0.5,
intervals = NULL,
iterator = NULL,
band = NULL,
intervals.set.out = NULL
)
Arguments
expr |
track expression for which quantiles are calculated |
percentiles |
an array of percentiles of quantiles in [0, 1] range |
intervals |
set of intervals |
iterator |
track expression iterator. If 'NULL' iterator is determined implicitly based on track expressions. |
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 calculates quantiles of 'expr' for each interval in 'intervals'.
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.
Value
If 'intervals.set.out' is 'NULL' a set of intervals with additional columns representing quantiles for each percentile.
