[R] factorial modeling of correlation matrices

[Bruno L. Giordano]

Hello,

I would greatly appreciate having some feedback on a problem.

My data consist of two matrices of robust rank correlations between data
collected in different conditions.

The two matrices represent data from two between-subjects conditions.

Each of the matrices correlates data from each of four within-subjects 
conditions, given by the factorial combination of two within-subjects 
factors.

I would like to test the significance of the effects of my experimental
factors, and of their two- and three-way interactions on the observed
correlations.

Now, am I missing some basics of multivariate statistics or I should 
seriously consider structural equations modeling, which seems an 
overkill for my problem?

Thank you very much,

	Bruno
