modeCenter {genoset} | R Documentation |
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.
