Hello everyone,
I am also trying to do within subjects repeated measures anova followed by
the
test of sphericity (see sample dataset attached below) and I am facing some
problems.
I tried to assign the example to my research question, but could not really
solve it.

Hi Mike,
I tried to run my data in SPSS and it works fine without any problems,
plug in my levels, plug in my covariate (since it is all within) and
get my Mauchly Tests.
I tried to rearrange the data so it looks like this

subject treatment day1 day2 da
No luck as in...? What error did you encounter?
In your example data set, you only have 2 levels of each within-Ss
factor, in which case you shouldn't expect to obtain tests of
sphericity; as far as I understand it, sphericity necessarily holds
when for repeated measures with only 2 levels and tes

Have you tried ezANOVA from the ez pacakge? It attempts to provide a
simple user interface to car's ANOVA (and when that fails, aov).
