ContactMatrix-distances: Compute linear distances from ContactMatrix objects

In LTLA/InteractionSet: Base Classes for Storing Genomic Interaction Data

Compute linear distances from ContactMatrix objects

Description

Methods to compute linear distances between pairs of interacting regions in a ContactMatrix object.

Usage

## S4 method for signature 'ContactMatrix'
pairdist(x, type="mid")

## S4 method for signature 'ContactMatrix'
intrachr(x)

Arguments

x	A ContactMatrix object.
type	A character string specifying the type of distance to compute. See ?pairdist,InteractionSet-method for possible values.

Details

pairdist,ContactMatrix-method will return a matrix of integer (or, if type="intra", logical) values. Each entry of this matrix specifies the distance between the interacting loci that are represented by the corresponding row and column. If type="intra", each entry indicates whether the corresponding interaction is intra-chromosomal. Running intrachr(x) is equivalent to pairdist(x, type="intra") for any ContactMatrix object x. See pairdist,InteractionSet-method for more details on the type of distances that can be computed.

Value

An integer or logical matrix of the same dimensions as x, containing the specified distances.
