multiple comparisons on a between factor
...self
unable to resolve in R so i hope to get some valuable insights from you. i
run an ANOVA with four factors; factor4 is an between factor (two different
groups measured), the others are withins (tested across /all/ subjects).
accordingly, my model looks as follows:
fm1
<-aov(dataSubjects~(factor1*factor2*factor3*factor4)+Error(subject/(factor1*
factor2*factor3))+factor4,data=mydata)
print(summary(fm1))
so far so good. i now would like to perform multiple comparisons, but
separately for each level of factor4 (two). this is how I do it: i sort out
(using subset) the...

Dear list,
i have a quick and (hopefully) straightforward question regarding the
plot-function after running aov. if i plot an equation like this:
plot(dataSubjects~factorA, data=mydata)
R gives me the boxplots for this particular factor A. my model, however
contains several factors. is there a straightforward way to plot barplots
for a specific factor with the constraint that those values are taken from
only the cells of a second factor B? for instance, if...
