[BioC] exporting data from limma and among slide normalization

[Christian Landry]

Hi,

I would like to know how to export non log transformed data from limma 
after normalization.

Also, I would like to know if any of you have experience with among slide 
normalization for cDNA microarrays experiment as implemented in limma. This 
seems intuitively important but I would like to know what are the potential 
drawbacks, if any.

Thanks for your help,

Christian
