Hi R-Community: Here is what I want to do: Every time I start R I want R to: 1. remove(list=ls()), and 2. "source" another file automatically. Then, when I shutdown R, I want R to: 1. remove(list=ls()) How do I do this? I recall vaguely that S could do this, but I don't remember exactly how it worked. Thanks for your help! Phil Smith
