Thanks to Peter, David, and Michael! After having corrected the coding
error, the p values converge to particular value, not necessarily
zero. The whole story is, 634 respondents in 6 different areas marked
their answer on a 7-step Likert scale (very bad, bad, ..., very good
-- later recoded to 5 scale levels). The statistical question now is,
do the answer's distributions (amount of goods, bads etc.) in either
area differ from the "mean" answer-distribution calculated with
summing up all goods, bads, etc. Anyway an omnibus chi square would
not answer my question, and due to spurious significances I'd rather
go back to my chi square book ;-) (for the interested, see http://sozmod.eawag.ch/files/file.Robj
for the entire table).
Thanks for your help
