You are requested not to crosspost at multiple R mailing lists (and by extension of the reasoning behind that request, crossposting on Rhelp and StackOverflow is also considered discourteous.)

Both Rhelp and SO expect yopu to provide enough information to comment intelligently, but you have not lived up to that expectation.
