I am not aware that R really does symbolic manipulation in the way which you want, but I would have thought that this process would make a very pretty little problem to solve for you yourself, in that you could write a programme to analyse the original expression as a string of characters, whose particular nature means that you have to make certain choices. Start with a simple example, say (x^2 + x +1)/(x+1) (i haven't actually worked this out) and gradually work up
