Dear David, Thanks for your response and warnings.
I will obey the rule and be a good citizen. Best, Jian-Feng, Because you have a poorly posted problem. As far as I can tell you have not yet responded constructively to the attempts at clarification of the problem. Cross-posting to this list after waiting only 4 hours with an identical problem is bad Rhelp behavior. You should use the interactive facilities at SO and better respect the efforts already being extended on your behalf. > > > >> I expect to hearing your helps/advice/directions in email or response in >> stackoverflow webpage.
