Rafael,
I think that is a good idea. If you make it a fairly simple
interface to write.table it shouldn't be too hard
write.exprs(eset, file="", ...)
write.table(exprs(eset), file, ...)
seems like enough for a start.
If you know of particular formats for different packages, such as
genespring then writing specialized, named functions for those
would be a good thing
