Hello, The first is easy.

But first make a file names vector. (I've used the file extension 'dat'.) test <- process.all(lst, m) fl.names <- paste(names(test), "dat", sep=".") lapply(seq_len(length(test)), function(i) write.table(test[[i]], fl.names[i], ...))

I'm a mathematician (with 6 semesters of stats). When I go to France, it's more to Charente-Maritime - Cognac, I have friends there, and I'll definitelly have a couple of cognacs on you. Good luck with your assignment.
