Dear J Zhang,
I'm a PhD student.
I was looking for a package that provides functions to identify minimum common
genomic regions of interests based on segmented copy number data from
multiple samples. I've found yours could be very useful for me.
Your Manual shows how to generate the segment data based on raw data using
DNAcopy package, and then, use these segment data (as a DNAcopy class object)
as the input to the cghMCR function. My problem is I've generated the segment
list using other method. This segment list has the same parameters than the
segment list you use as example (called "segData") but it is a data frame
object, not a DNAcopy object like "segData".
How could I apply cghMCR and MCR functions using my R data frame? There is
some method to get a DNAcopy class object from my segment list?
