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).
