i upload the data file kew.dat, and with this file the question ask me to:

1)use a suitable graphical technique to display the disturbtions of rainfall
amounts in each month of the year. If possible, ensure the months appear in
the right order (month.abb maybe useful).

2)Without using the kruskal.test command, perform a Kruskal-Wallis test to
see whether there is evidence for differences in rainfall disturbution
between months (include i)the vaule of test statistic, ii) degrees of
freedom for the chi-squared approximation that we are using, iii) critical
values for 5% and 1% tests and iv) p-value for this test).

Please, many many thanks to anyone of you.
