[BioC] Partitioning main effects.

I am doing analysis of variance. Suppose y is an observed probe
intensity value then a main effects model is
y = Array + probe + error
Suppose there is information about the locations of probes relative to
3' end and suppose the distances from 3' fall in 2 categories (X,Y). I
am searching for a code that will enable me to partiotion probe-effect
on the basis of the distance categories (X,Y).
I want to have ANOVA table of the form, say
Sources of variation DF SS MSS F
Array 20 A
Probe 30 B
X 10 C
Y 20 D
where C+D = B.
Thanks for your help. Stephen.
