r-bioc-dnacopy - 1.56.0-1 main

Implements the circular binary segmentation (CBS) algorithm to segment DNA
copy number data and identify genomic regions with abnormal copy number.
.
This package is for analyzing array DNA copy number data, which is usually
(but not always) called array Comparative Genomic Hybridization (array CGH)
data It implements a methodology for finding change-points in these data which
are points after which the (log) test over reference ratios have changed
location. This model is that the change-points correspond to positions where
the underlying DNA copy number has changed. Therefore, change-points can be
used to identify regions of gained and lost copy number. Also provided is a
function for making relevant plots of these data.
