Thanks for all of your help, David, I finally got it. Here's some generic syntax in case it helps someone else down the road (using a 4-way ANOVA with repeated measures on all factors): # LOAD DATA data <- read.table("PATH\\datafile.txt") # RUN THE ANOVA data.aov <- aov(y ~ factor(x1)*factor(

Hi all, I'm quite new to R and have a very basic question regarding how one gets the standard error of the mean for factor levels under aov. I was able to get the factor level means using: summary(print(model.tables(rawfixtimedata.aov,"means"),digits=3)), where rawfixtimedata.aov is my aov m
