Hello everyone:
                            I'm a new member of this group.
                            Following the question(2) of Amit Patel-7,
                            I know "oneway.test" has the option of
                            Maybe it's can be the answer of this question!
                            But, I have a question about "oneway.test",
                            How can I get "SS", and "MS" information from
                            R code and the results are as follows. 
                            Thank you very much.  :)

F = 56.2191, num df = 4, denom df = 20, p-value = 1.345e-10

        One-way analysis of means (not assuming equal variances)
