Re: [R] Deleted objects keep coming back
When you start you R session, see if it says [Previously saved workspace restored] immediately before the first command prompt. I think the only way a workspace can be restored automatically is if you used save.image() at some point, in which case it would save all objects as a hidden file called ".RData". Another way a different workspace would have been saved if it was specified in .Rprofile, Rprofile.site. See help(Startup) for more information about the order of files that R reads in.

Yes, but I think you'd be better off to learn about R's command line argument in particular --no-restore and --vanilla. If you're not starting R from the command line, I'm sure there's a way to pass arguments anyway... -- O__ Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200 Cph.

RE: [R] Deleted objects keep coming back
Ah! I think this is what happened -- whenever I restarted R, it would automatically load the previous workspace and its objects (call this workspace 1). Then, when I would attempt to load another workspace (call this workspace 2), it would retain the objects from workspace 1 in ADDITION to the objects loaded from workspace 2. If I load up R, it will say previous workspace restored. If I then type >rm(list=ls()) to delete all objects, and then load another workspace, it will only have the objects from the workspace I loaded... Am I correct here?
