[BioC] Plot signal distribution in miRNA arrays

[andrea.grilli at ior.it]

Hi to all,

I would like to plot signal distribution from miRNA array experiment,  
one only plot for all arrays. Any suggestion on how to perform it? Is  
there some easy way to check how this data fit a normal distribution  
(e.g. with K-S test)?

Data comes from Agilent Human miRNA v.2, normalized with quantile  
method and log2 transformed.

Thanks in advance,
Andrea
