modeCenter {genoset} | R Documentation

## Center continuous data on mode

### Description

Copynumber data distributions are generally multi-modal. It is often assumed that the tallest peak represents 'normal' and should therefore be centered on a log2ratio of zero. This function uses the density function to find the mode of the dominant peak and subtracts that value from the input data.

### Usage

    modeCenter(ds)

### Arguments

`ds` | numeric matrix

### Value

numeric matrix

### Examples

      modeCenter( matrix( rnorm(150, mean=0), ncol=3 ))
