[BioC] AffyBatch <-> exprSet

[Igor Androv]

Hi list!

After reading in may data, which is an affybatch object HG-U133A with 20 
samples (2 groups with 10 samples), I have no problems in visualizing my 
data (e.g. with boxplots, MAplots,...). After normalizing my data sets with 
gcrma I now have an exprSet object and I don´t have a clue in which ways I 
can visualize the exprSet. Or is there a possibility to normalize my data 
without changing it into an exprSet?

I haven´t found proper information on the i-net that is why I have to bug 
you, but a link with good examples would be great too!

thank you very much in advance!

sincere,
igor
