Co-Inertia Analysis

I am using Co-Inertia Analysis (CIA) to study the co-structure between a
faunistic (22 taxa, 10 sampling stations, 4 dates) and an environmental
data set (14 parameters, 10 stations, 4 dates). I am able to run the
"standard" CIA, but in a next step, I would like to take into account the
spatial and temporal effects using between- and within- analyses.
Therefore, my question are:
1. How to arrange and prepare the data files?
2. How to run the different analyses?

Many thanks,

Peter Burgherr
