Reduce Overlapping Ranges

Merge overlapping or adjacent ranges.

Usage

fast_reduce(x, ignore_strand = FALSE, min_gap_width = 1L, with_revmap = FALSE)

Arguments

x

An IRanges or GRanges object.

ignore_strand

Logical scalar. Ignored for non-genomic ranges.

min_gap_width

Integer scalar controlling when nearby ranges should be merged.

1 merges overlapping or directly adjacent ranges.

Larger values require larger gaps before two ranges are kept separate.

with_revmap

Logical scalar. If TRUE, include reverse mapping from each output range back to contributing input ranges.

Value

An object of the same range class as x.

Details

fast_reduce() simplifies a range set by merging runs of overlapping or near-adjacent intervals.

Examples

x <- IRanges::IRanges(start = c(1, 4, 10), end = c(5, 8, 12))
fast_reduce(x)
#> IRanges object with 2 ranges and 0 metadata columns:
#>           start       end     width
#>       <integer> <integer> <integer>
#>   [1]         1         8         8
#>   [2]        10        12         3
