摘要: This document presents an overview of the DNAcopy package. package is for analyzing array DNA copy number data, which usually (but not always) called Comparative Genomic Hybridization (array CGH) data (Pinkel et al., 1998; Snijders 2001; Lucito 2003). It implements our methodology finding change-points in these (Olshen 2004), are points after (log) test over reference ratios have changed location. Our model that correspond to positions where underlying has changed. Therefore, can be used identify regions gained and lost number. We also provide a function making relevant plots data.
