Unites two sets of 2D intervals

Unites two sets of two-dimensional intervals.

Usage

gintervals.2d.union(intervals1 = NULL, intervals2 = NULL)

Arguments

intervals1, intervals2

two-dimensional intervals (a data frame or the name of an intervals set)

Value

A data frame with the six 2D interval columns, sorted as by gintervals.2d.

Details

Concatenates 'intervals1' and 'intervals2' and returns the combined set sorted as by gintervals.2d. Overlapping rectangles are not merged: because the union of two rectangles is not generally a rectangle, the result is simply the combined set (unlike the 1D gintervals.union).

Examples

a <- gintervals.2d("chr1", 0, 1000, "chr2", 0, 1000)
b <- gintervals.2d("chr1", 500, 1500, "chr2", 500, 1500)
gintervals.2d.union(a, b)
#>   chrom1 start1 end1 chrom2 start2 end2
#> 1   chr1      0 1000   chr2      0 1000
#> 2   chr1    500 1500   chr2    500 1500
