[BioC] expression output in simpleaffy

[botto]

Hi Tarun,

I'm not quite sure what you are looking for. Do you mean the "expression
levels" alias "normalised intensisities"? If that is so then you can
access these values with 

> exprs(yourExprSetObject)

It returns an array of the dimensions numberofgenes x numberofarrays.
Note that these values are normalised AND summarised. If you wish
unsummarised values, just normalised, then you have to set
summary.method=NULL when you call expresso.

Hope that helps,

Benjamin
