I'm sorry, I don't know how to copy it to the list.
as for the output and functions I've used:
Use the Cc:! I am NOT answering list questions in private mails.
-p
dm<-aov(value~(exposure*Treatment*Strain)+Error(subject/exposure) +
(Strain*Treatment), mdata)
(* exposure=distance)
then I do : summary(dm)
Thank you very much for your patient.

Did you copy this to the list? Otherwise, please do. Again, please
show the output and model spec.

I finally understood what I didi wrong - I used a numerical
variable as the sibject variable, adding a factor subject
variable fixed the issue.
one the same analysis, how can I check for simple main effect?
here is my data:

Hi,
I just started with R and I found that there are many
options to
rearrange
the data to do mixed models.
I want to use the reshape function. I have 2 between
subject
variables and
one within.
I was able to change the data structure but still - the
result
of the aov
functions are calculating everything as a within
subject.
the table looks like this:
SerialNo breed treatment distance_1
distance_2
1 c57 dfp 235 3253
etc.
I changed it to look like this:
SerialNo breed treatment exposure distance
1 c57 dfp
1 235
1 c57 dfp
2 3253
etc.
Then I do:
dt<-aov(distance~(exposure*treatment*breed)
+Error(SerialNo/exposure)
+
(treatment*breed), dataframe)
what am I doing wrong?
For a start, not showing us the output.... Also not
showing us
enough of the data and not convincing us that you are
actually using
the reshaped data frame.
