[BioC] A beginner's question about assigning values to marray slots

I just started using bioconductor for microarray analysis. First the gpr
file was read with marray package, next background was corrected using
smida which returns a vector.  When the vector was assigned back to
marray at maRf, I got an error in checkSlotAssignment. But I can do it
element-wise (e.g., marray at maRf[1]<-vector[1],
marray at maRf[2]<-vector[2], etc.).
