Hello all!!

How do I get access to the individual probe intensities in my data object 
(which I get with the
data<-ReadAffy() command) ?

I know that I can get them with the mm() and pm() functions but if I would 
like to see,filter,remove or change the data in the data object, how is 
this accomplished?

Essentially: How is the data object built up and how do you access it??

Another question: How and where is the background value stored/calculated??
