Calculates a union of two sets of intervals

Calculates a union of two sets of intervals.

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

Value

If 'intervals.set.out' is 'NULL' a data frame representing the union of intervals.

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.

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")
