Hi, all; I got a reply for my previous several postings saying that I was spamming the r-help mailing list. I am very sorry to all subscribers if I did that. But I've been reposting my message to the mailing list several times because I didn't know whether my help post was actually posted or not. I remember from my previous experiences that, when I post a message, I can see my own posting myself. But this time, I didn't see my own message so I thought my message got dropped for some reasons. Was there any change in r-help mailing system configuration?
