[R] Cannot grasp how to apply "by" here...

Obviously, A cannot assign a row name because the dimensions do not
agree. I can use rownames(vector) <- x$Name[1] though.

then things get calculated (I saw it with browser()) but rbind does
not do what I want it to do, "results" remains numeric().

why?
