I have some problem with reading my CEL files (hu6800). I use ReadAffy(widget=TRUE) for reading files, but when I read all files, I see an Error: Error in initialize(value, ...) : Cel file C:/Program Files/R/rw1090/rdata/2001.CEL does not seem to be of HU6800 type But when I'm trying to add these files one by one it's ok. I appreciate any help!! Vitalina. [[alternative HTML version deleted]]
