OK! Thank you for your generous help.

[R] How to get the SS and MS from oneway.test?
Hello everyone: I'm a new member of this group. I have a question about "oneway.test". When I use "anova(lm())" to analysis the ANOVA, I can get the information about Sum Sq and Mean Sq. (The R code and the results are as follows.) > anova(lm(BackCalac~factor(Assay),data=Control)) Analysis of Variance Table Response: BackCalac Df Sum Sq Mean Sq F valuePr(>F) factor(Assay) 4 270.846 67.711 56.219 1.345e-10 *** Residuals 20 24.088 1.204 But it default the variances are the same. If the variances aren't equal. I need to use the "oneway.test" method. Because oneway.test has the option about "var.equal=F". Here, I have a question about "oneway.test", How can I get "SS", and "MS" information from "oneway.test"? My R code and the results are as follows. Thank you very much. :) > oneway.test(BackCalac~factor(Assay), var.equal=T,data=Control) One-way analysis of means data: BackCalac and factor(Assay) F = 56.2191, num df = 4, denom df = 20, p-value = 1.345e-10 > oneway.test(BackCalac~factor(Assay), var.equal=F,data=Control) One-way analysis of means (not assuming equal variances) data: BackCalac and factor(Assay) F = 92.8834, num df = 4.000, denom df = 9.625, p-value = 1.165e-07 -- View this message in context: http://r.789695.n4.nabble.com/How-to-get-the-SS-and-MS-from-oneway-test-tp4544417p4544417.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] Help with ANOVA in R
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 "var.equal=F". 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 "oneway.test"? R code and the results are as follows.
