Dear Group,
I saw this question asked but did not find a reply and I have the same
question.
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 cghMCR package could be very useful for me.
The 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:
1)the sample id,
2)the chromosome number,
3)the map position of the start of the segment,
4)the map position of the end of the segment,
5)the number of markers in the segment
6)the average value in the segment
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? Is there
some method to get a DNAcopy class object from my segment list?

Thanks,
Viritha
