Ditto for me, with the following exceptions: - I always use save(..., compress=TRUE), without exception. - The only time I'd use save.image() is when I need to break a remote connection on short notice. - I have not used options() to set the default simply because I have not figured out how exactly to do it. From what I remember, the doc simply says it can be done, but does not explicitly say how.
