gintervals.union: Calculates a union of two sets of intervals

In misha: Toolkit for Analysis of Genomic Data

Calculates a union of two sets of intervals

Description

Calculates a union of two sets of intervals.

Usage

gintervals.union(
  intervals1 = NULL,
  intervals2 = NULL,
  intervals.set.out = NULL
)

Arguments

intervals1, intervals2	set of one-dimensional intervals
intervals.set.out	intervals set name where the function result is optionally outputted

Details

This function returns intervals that represent a genomic space covered by either 'intervals1' or 'intervals2'.

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 data frame representing the union of intervals.

Examples

gdb.init_examples()

intervs1 <- gscreen("dense_track > 0.15 & dense_track < 0.18")
intervs2 <- gscreen("dense_track >= 0.18 & dense_track < 0.2")

## 'intervs3' and 'intervs4' are identical
intervs3 <- gintervals.union(intervs1, intervs2)
intervs4 <- gscreen("dense_track > 0.15 & dense_track < 0.2")
