Hello, I never explicitly use that class in my function. I did debugging and realised what the problem is. DGEList is part of class hierarchy and it inherits from the superclass LargeDataObject
> showClass("DGEList") Class "DGEList" [package "edgeR"] Slots: Name: .Data Class: list Extends: Class "list", from data part Class "LargeDataObject", directly Class "vector", by class "list", distance 2 That's why edgeR needs to know about that class. -------------------------------------- Dario Strbenac PhD Student University of Sydney Camperdown NSW 2050 Australia _______________________________________________ Bioc-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/bioc-devel
