I'm in favor of such a change. I almost always explicitly set `compress = TRUE'. When I don't use it, it's because I want to be able to load large objects quickly and I've noticed that loading uncompressed workspaces can be quite a bit faster. Usually though, the savings in disk space is worth the small penalty in loading time. > > Should we also change the default in save.image()?

I rarely use `save.image()' except to occasionally dump data during a long run for crash recovery purposes.
