In bernatgel/regioneR: Association analysis of genomic regions based on permutation tests

Number Of Overlaps

Description

Returns the number of regions in A overlapping any region in B

Usage

numOverlaps(A, B, count.once=FALSE, ...)

Arguments

A	a region set in any of the formats accepted by toGRanges (GenomicRanges, data.frame, etc...)
B	a region set in any of the formats accepted by toGRanges (GenomicRanges, data.frame, etc...)
count.once	boolean indicating whether the overlap of multiple B regions with a single A region should be counted once or multiple times
...	any additional parameters needed

Value

It returns a numeric value that is the number of regions in A overlapping at least one region in B.
