R help - Mar 2008 - LIMMA: array spot summary options beyond duplicateCorrelation()

Hello Limma users

A quick question, I hope:

I have dual-channel spotted expression arrays in a simple loop design 
(no dye swaps), viz:

1 vs reference
2 vs 1
3 vs 2
reference vs 3

There are 4 replicate spots for each probe on each array.

It seems as if getting meaningful spot summary results using 
duplicateCorrelation() is not possible in my case as the spots are not 
regularly spaced, and I don't *really* have enough arrays, no?

So then what are my other options in Limma to summarise replicated spots?

Thanks,
Quin
