plyranges (version 1.9.3)

pair_overlaps: Pair together two ranges objects

Description

Pair together two ranges objects

Usage

pair_overlaps(x, y, maxgap, minoverlap, suffix)
pair_nearest(x, y, suffix)
pair_precede(x, y, suffix)
pair_follow(x, y, suffix)

Arguments

x, y

Ranges objects to pair together.

maxgap, minoverlap

The maximimum gap between intervals as an integer greater than or equal to negative one. The minimum amount of overlap between intervals as an integer greater than zero, accounting for the maximum gap.

suffix

A character vector of length two used to identify metadata columns coming from x and y.

Value

a DataFrame with two ranges columns and the corresponding metadata columns.

Details

These functions return a DataFrame object, and is one way of representing paired alignments with plyranges.
