full2sparse {HiCcompare} | R Documentation

## Transfrom a full Hi-C contact matrix to a sparse upper triangular matrix

### Description

Transfrom a full Hi-C contact matrix to a sparse upper triangular matrix

### Usage

    full2sparse(mat)

### Arguments

`mat` | A matrix. Must have column names equal to the start location for each bin. i.e. for a 6x6 Hi-C matrix where the first region starts at 0 kb and the final region starts at 500KB and the resolution is 100kb, the column names of the matrix should be as follows: colnames(mat) = c(0, 100000, 200000, 300000, 400000, 500000)

### Value

A sparse upper triangular matrix.

### Examples

    m <- matrix(1:100, 10, 10)
    colnames(m) <- 1:10
    sparse <- full2sparse(m)
    sparse
