binMatrix {genomation} | R Documentation

## Bins the columns of a matrix using a user provided function

### Description

Bins the columns of a matrix using a user provided function

### Usage

    binMatrix(x, bin.num = NULL, fun = "mean")

    ## S4 method for signature 'ScoreMatrix'
    binMatrix(x, bin.num = NULL, fun = "mean")

    ## S4 method for signature 'ScoreMatrixList'
    binMatrix(x, bin.num = NULL, fun = "mean")

### Arguments

`x` | `ScoreMatrix` or a `ScoreMatrixList` object
`bin.num` | `integer` number of bins in the final matrix
`fun` | `character` vector or an anonymous function that will be used for binning

### Value

`ScoreMatrix` or `ScoreMatrixList` object

### Examples

    # binning the columns in a ScoreMatrix object
    library(GenomicRanges)
    target = GRanges(rep(c(1,2),each=7), IRanges(rep(c(1,1,2,3,7,8,9), times=2), width=5),
    weight = rep(c(1,2),each=7),
    strand=c('-', '-', '-', '-', '+', '-', '+', '-', '-', '-', '-', '-', '-', '+'))
    windows = GRanges(rep(c(1,2),each=2), IRanges(rep(c(1,2), times=2), width=5),
    strand=c('-','+','-','+'))
    sm = ScoreMatrix(target, windows)
    bin = binMatrix(sm, bin.num=2)
