mat2df: Transform the contacts of a 'dgTMatrix' into a 'data.frame'

In qenvio/dryhic: Some Functions to Handle HiC Data

Description

This function takes a sparse matrix of contacts and transforms it into a data.frame. It works only with matrices of one chromosome.

Usage

mat2df(mat, b = NULL, both = FALSE)

Arguments

mat	A dgTMatrix of contacts with genomic bins as row.names.
b	An optional vector of genomic position (otherwhise, it uses the information contained in the row.names.
both	A logical indicating if both (bin index and position) should be returned.

Details

Please note that mat is expected to be a matrix of one chromosome (you could obtain one using subset_matrix).

Value

A data.frame with the two coordinates (i and j) and the number of contacts (x).
