[BioC] protein and peptide mass spectrometry

i have used the Biobase package to keep spectra as exprSet objects. not 
much adaptation was required. in the exprs  slot I use the gene dimension 
(rows) for the different spectral mass and  the array dimension (columns) 
for the different spectra. the subject  information  goes into the 
phenoData slot. you can then, for example, 
1) use genefilter to do feature selection, 
2) choose from the many  classification functions in R to classify samples, 
3) take advantage of R graphics.
4) etc.. 

let me know if you want to discuss this further...
