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...
