Hello, R-i-zens. I'm working on an data set with a factorial ANOVA that has a significant interaction. I'm interested in seeing whether the simple effects are different from 0, and I'm pondering how to do this. So, I have my.anova<-lm(response ~ trtA*trtB) The output for which gives me a number of coefficients and whether they are different from 0. However, I want the simple effects only, incorporating their intercepts, with their error estimates. Can I somehow manipulate this object to get that? Or, would a good shortcut be my.sim...

I'm still relatively new to R but was wondering if anyone could help me force R to compute the f-statistic etc using the the nested term rather than the residual. In my particular case we were nesting a treatment effect by a replicated tank which was not non-significant enough (p>0.25)to be dropped from the statistical model. Here's my code:

Dear R People: I have an AOV model that I get confidence intervals from via > confint(chick1.aov1) 2.5 % 97.5 % trtA 1.472085 1.607915 trtB 1.512085 1.647915 trtC 1.328751 1.464582 > I am using R2HTML to produce HTML output. However, the HTML code itself just has rounded values, i.e., 1.5 and 1.6. Has anyone run across this, please? Any suggestions would be much appreciated. Sincerely, Erin -- Erin Hodge...

Hello all, I have a question concerning how to get the P-value for a explanatory variables based on GLM. I'll run multiple regressions with GLM, and I'll need the P-value for the same explanatory variable from these multiple GLM results. I check the help and there are quite a few Value options but I just can not find anyone about the p-value. Could anyone help me with that?
