[BioC] Help needed: Beadarray

[Na, Jie]

Hi list,

I have questions about beadarray package that I hope to get some answer or
helpful hint from this list.

1. Where is the function DiffScore? I don't seem to be able to find this
function although it was mentioned in the document "beadarray: An R package
to Analyse Illumina BeadArrays"2006.
2. I want to make pair-wise comparisons between arrays.  I have the bead
level data available.
A. Is background subtraction with background normalization is recommended?
B. If here is no such function of DiffScore existing any more, should I do
modified t-test on the summarized data on the beadlevel data?

Thanks,

Jeanie
