[R] File Reading Problem

[Jiming Yu]

    Thank you very much. I think it's working by using:

mytry<-readBin("Source.txt", n=2325120, size=1, what="int")

    where n is the maximum size of the text file. So there may be no big
bugs here.
    I'd really appreciate your help. Thanks.
                Jiming
