Dear Carlos,

>From your check results:

        cbc.data <- cbc.read.table( system.file("data",
        "cbc.test.data.txt", package = "colbycol"), sep = "\t" )
                Warning in file(file, "r") :
                cannot open file '0001': No such file or directory
I think you're trying to read the file "cbc.test.data.txt" located in
the folder "data" of your package skeleton. Is that right? If so, maybe

        paste(system.file(package = "colbycol"),
        "data/cbc.test.data.txt", sep="/")
will solve your issue - although I didn't try.
