I am having trouble getting standard errors for expressions.  I used the
following commands:

data<-ReadAffy(widget=TRUE) (Read in 2 sets of duplicate arrays, 4 total)

A matrix (of the appropriate dim) is returned, but all the entries are NA.
I also tried using the expresso command (for MAS preprocessing) and got
the same results.

Any suggestions?
BTW, are duplicate arrays required in order to get standard errors?
